Isolated DC/DC converters. Ericsson Power Modules DC/DC converters and DC/DC regulators are designed in accordance with safety standards IEC/EN/UL 60 950, Safety of Information Technology Equipment. It is recommended that a fast blow fuse with a rating twice the maximum input current per selected product be used at the input of each DC/DC converter. If an input filter is used in the circuit the fuse should be placed in front of the input filter. In the rare event of a component problem in the input filter or in the DC/DC converter that imposes a short circuit on the input source, this fuse will provide the following functions: IEC/EN/UL60950 contains requirements to prevent injury or damage due to the following hazards: * * * * * * Electrical shock Energy hazards Fire Mechanical and heat hazards Radiation hazards Chemical hazards * Isolate the faulty DC/DC converter from the input power source so as not to affect the operation of other parts of the system. * Protect the distribution wiring from excessive current and power loss thus preventing hazardous overheating. The galvanic isolation is verified in an electric strength test. The test voltage (VISO) between input and output is 1500 Vdc or 2250 Vdc for 60 seconds (refer to product specification). Leakage current is less than 1A at nominal input voltage. On-board DC-DC converters are defined as component power supplies. As components they cannot fully comply with the provisions of any Safety requirements without "Conditions of Acceptability". It is the responsibility of the installer to ensure that the final product housing these components complies with the requirements of all applicable Safety standards and Directives for the final product. 24 V dc systems. The input voltage to the DC/DC converter is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions. Component power supplies for general use should comply with the requirements in IEC60950, EN60950 and UL60950 "Safety of information technology equipment". 48 and 60 V dc systems. If the input voltage to Ericsson Power Modules DC/DC converter is 75 V dc or less, then the output remains SELV (Safety Extra Low Voltage) under normal and abnormal operating conditions. There are other more product related standards, e.g. IEC612047 "Safety standard for power supplies", IEEE802.3af "Ethernet LAN/MAN Data terminal equipment power", and ETS300132-2 "Power supply interface at the input to telecommunications equipment; part 2: DC", but all of these standards are based on IEC/EN/UL60950 with regards to safety. Single fault testing in the input power supply circuit should be performed with the DC/DC converter connected to demonstrate that the input voltage does not exceed 75 V dc. If the input power source circuit is a DC power system, the source may be treated as a TNV2 circuit and testing has demonstrated compliance with SELV limits and isolation requirements equivalent to Basic Insulation in accordance with IEC/EN/UL 60 950. Ericsson Power Modules DC/DC converters and DC/DC regulators are UL 60 950 recognized and certified in accordance with EN 60 950. The flammability rating for all construction parts of the products meets UL 94V-0. Non-isolated DC/DC regulators. The products should be installed in the end-use equipment, in accordance with the requirements of the ultimate application. Normally the output of the DC/DC converter is considered as SELV (Safety Extra Low Voltage) and the input source must be isolated by minimum Double or Reinforced Insulation from the primary circuit (AC mains) in accordance with IEC/EN/UL 60 950. PKM 4000E PI Datasheet The input voltage to the DC/DC regulator is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions. It is recommended that a slow blow fuse with a rating twice the maximum input current per selected product be used at the input of each DC/DC regulator.

Layout Recommendation The radiated EMI performance of the DC/DC converter will be optimised by including a ground plane in the PCB area under the DC/DC converter. This approach will return switching noise to ground as directly as possible, with improvements to both emissions and susceptibility. It is also important to consider the stand-off of the PKM 4000E series DC/DC converter. If one ground trace is used, it should be connected to the input return. Alternatively, two ground traces may be used, with the trace under the input side of the DC/DC converter connected to the input return and the trace under the output side of the DC/DC converter connected to the output return. Make sure to use appropriate safety isolation spacing between these two return traces. The use of two traces as described will provide the capability of routing the input noise and output noise back to their respective returns.

At input voltages exceeding 75V, the power loss will be higher than at normal input voltage and TPcb must be limited to absolute max +110C. The absolute maximum continuous input voltage is 80Vdc. All PKM 4000E Series DC/DC converters have remote sense that can be used to compensate for moderate amounts of resistance in the distribution system and allow for voltage regulation at the load or other selected point. The remote sense lines will carry very little current and do not need a large cross sectional area. However, the sense lines on the PCB should be located close to a ground trace or ground plane. In a discrete wiring situation, the use of twisted pair wires or other technique to reduce noise susceptibility is highly recommended. The remote sense circuitry will compensate for up to 10% voltage drop between the sense voltage and the voltage at the output pins. The output voltage and the remote sense voltage offset must be less than the minimum over voltage trip point. If the remote sense is not needed the -Sense should be connected to -Out and +Sense should be connected to +Out. Turn-Off Input Voltage The PKM 4000E Series DC/DC converters monitor the input voltage and will turn on and turn off at predetermined levels. The minimum hysteresis between turn on and turn off input voltage is 2V where the turn on input voltage is the highest. Remote Control (RC) Output Voltage Adjust (Vadj) The PKM 4000E Series DC/DC converters have a remote control +In function referenced to the primary RC side (- In), with negative and positive logic options available. The RC -In function allows the converter to be turned on/off by an external device Circuit configuration like a semiconductor or mechanical for RC function switch. The RC pin has an internal pull up resistor to + In. The needed maximum sink current is 1mA. When the RC pin is left open, the voltage generated on the RC pin is 3.5 - 6 V. The maximum allowable leakage current of the switch is 50 A. All PKM 4000E Series DC/DC converters have an Output Voltage adjust pin (Vadj). This pin can be used to adjust the output voltage above or below Output voltage initial setting. When increasing the output voltage, the voltage at the output pins (including any remote sense offset) must be kept below the overvoltage trip point, to prevent the converter from shut down. Also note that at increased output voltages the maximum power rating of the converter remains the same, and the output current capability will decrease correspondingly. To decrease the output voltage the resistor should be connected between Vadj pin and -Sense pin. To increase the voltage the resistor should be connected between Vadj pin and +Sense pin. The resistor value of the Output voltage adjust function is according to information given under the output section. The standard converter is provided with "negative logic" remote control and the converter will be off until the RC pin is connected to the - In. To turn on the converter the voltage between RC pin and - In should be less than 1V. To turn off the converter the RC pin should be left open, or connected to a voltage higher than 4 V referenced to - In. In situations where it is desired to have the converter to power up automatically without the need for control signals or a switch, the RC pin can be wired directly to - In. The second option is "positive logic" remote control, which can be ordered by adding the suffix "P" to the end of the part number. The converter will turn on when the input voltage is applied with the RC pin open. Turn off is achieved by connecting the RC pin to the - In. To ensure safe turn off the voltage difference between RC pin and the - In pin shall be less than 1V. The converter will restart automatically when this connection is opened. +Out +Out +Sense +Sense Load Vadj Radj Load Vadj Radj -Sense -Sense -Out -Out Decrease Increase Circuit configuration for output voltage adjust PKM 4000E PI Datasheet 33 EN/LZT 146 051 R7A (c) Ericsson Power Modules, February 2007 Operating Information Current Limit Protection Maximum Capacitive Load The PKM 4000E Series DC/DC converters include current limiting circuitry that allows them to withstand continuous overloads or short circuit conditions on the output. The output voltage will decrease towards zero for output currents in excess of max output current (Iomax). The converter will resume normal operation after removal of the overload. The load distribution system should be designed to carry the maximum output short circuit current specified. When powering loads with significant dynamic current requirements, the voltage regulation at the load can be improved by addition of decoupling capacitance at the load. The most affective technique is to locate low ESR ceramic capacitors as close to the load as possible, using several capacitors to lower the effective ESR. These ceramic capacitors will handle short duration high-frequency components of dynamic load changes. In addition, higher values of electrolytic capacitors should be used to handle the mid-frequency components. It is equally important to use good design practise when configuring the DC distribution system. Low resistance and low inductance PCB (printed circuit board) layouts and cabling should be used. Remember that when using remote sensing, all resistance, inductance and capacitance of the distribution system is within the feedback loop of the converter. This can affect on the converters compensation and the resulting stability and dynamic response performance. As a "rule of thumb", 100F/A of output current can be used without any additional analysis. For example with a 25A converter, values of decoupling capacitance up to 2500 F can be used without regard to stability. With larger values of capacitance, the load transient recovery time can exceed the specified value. As much of the capacitance as possible should be outside the remote sensing loop and close to the load. The absolute maximum value of output capacitance is 10 000 F. For values larger than this, please contact your local Ericsson Power Modules representative. Over Voltage Protection (OVP) The PKM 4000E Series DC/DC converters have output overvoltage protection. In the event of an overvoltage condition, the converter will shut down immediately. The converter will make continuous attempts to start up (non-latching mode) and resume normal operation automatically. Over Temperature Protection (OTP) The PKM 4000E Series DC/DC converters are protected from thermal overload by an internal over temperature shutdown circuit. When the PCB temperature adjacent to the PWM control circuit exceeds 120 C the converter will shut down immediately. The converter will make continuos attempts to start up (non-latching mode) and resume normal operation automatically when the temperature has dropped >10C below the temperature threshold. Input And Output Impedance The impedance of both the power source and the load will interact with the impedance of the DC/DC converter. It is most important to have a ratio between L and C as low as possible, i.e. a low characteristic impedance, both at the input and output, as the converters have a low energy storage capability. The PKM 4000E Series DC/DC converters have been designed to be completely stable without the need for external capacitors on the input or the output circuits. The performance in some applications can be enhanced by addition of external capacitance as described under maximum capacitive load. If the distribution of the input voltage source to the converter contains significant inductance, the addition of a 100F capacitor across the input of the converter will help insure stability. This capacitor is not required when powering the DC/DC converter from a low impedance source with short, low inductance, input power leads. PKM 4000E PI Datasheet Parallel Operation The PKM 4000E Series DC/DC converters can be paralleled for redundancy if external o-ring diodes are used in series with the outputs. It is not recommended to parallel the PKM 4000E Series DC/DC converters for increased power without using external current sharing circuits. 34 EN/LZT 146 051 R7A (c) Ericsson Power Modules, February 2007 Thermal Consideration General Calculation of ambient temperature The PKM 4000E Series DC/DC converters are designed to operate in a variety of thermal environments, however sufficient cooling should be provided to help ensure reliable operation. Heat is removed by conduction, convection and radiation to the surrounding environment. Increased airflow enhances the heat transfer via convection. The available load current vs. ambient air temperature and airflow at Vin=53 V for each model is according to the information given under the output section. The test is done in a wind tunnel with a cross section of 305x305mm, the DC/DC converter vertically mounted on a 8 layer PCB with a size of 254x254mm. Proper cooling can be verified by measuring the temperature of selected devices. Peak temperature can occur at position P1 and P2. The temperature at these positions should not exceed the recommended max values. By using the thermal resistance the maximum allowed ambient temperature can be calculated. Position Device Tcritical 1.The powerloss is calculated by using the formula ((1/) - 1) x output power = power losses. = efficiency of converter. E.g 89% = 0.89 2.Find the value of the thermal resistance for each product in the diagram by using the airflow speed at the output section of the converter. Take the thermal resistance x powerloss to get the temperature increase. 3.Max allowed calculated ambient temperature is: Max TPCB of DC/DC converter - temperature increase.

When wave soldering is used max temperature on the pins is specified to 260C for 10 seconds. Maximum preheat rate of 4C/s and temperature of max 130C is suggested. When hand soldering, care should be taken to avoid direct contact between the hot soldering iron tip and the pins for more than a few seconds in order to prevent overheating. The Mean Time Between Failure (MTBF) of the PKM4000E Series DC/DC converter is calculated at full output power and an operating ambient temperature (TA) of +40C. Different methods could be used to calculate the predicted MTBF andv failure rate which may give different results. Ericsson Power Modules currently uses two different methods, Ericsson failure rate data system DependTool and Telcordia SR332. Predicted MTBF for the PKM4000E Series products is: 7.0 million hours according to DependTool. 1.6 million hours according to Telcordia SR332, issue 1, Black box techique. No-clean flux is recommended to avoid entrapment of cleaning fluids in cavities inside of the DC/DC power module. The residues may affect long time reliability and isolation voltage. The Ericsson failure rate data system is based on field tracking data. The data corresponds to actual failure rates of components used in Information Technology and Telecom (IT&T) equipment in temperature controlled environments (TA = -5...+65C). Telcordia SR332 is a commonly used standard method intended for reliability calculations in IT&T equipment.The parts count procedure used in this method was originally modeled on the methods from MIL-HDBK-217F, Reliability Predictions of Electronic Equipment. It assumes that no reliability data is available on the actual units and devices for which the predictions are to be made, i.e. all predictions are based on generic reliability parameters.equipment.
