However, the relationship between TA and TC depends heavily on the conditions of operation and integration into a system. The thermal conditions are influenced by input voltage, output current, airflow, temperature of surrounding components and surfaces. TA max is therefore, contrary to TC max, an indicative value only. The output power of LOK models must be derated at low input voltage, see figure below. 05154a Po allowed /Po nom 1.0 0.85 0.5 The relation between the maximum allowed output power Po allowed and the temperature TA of the surrounding air is given in the figure below.

Fig. 3 Maximum allowed output power versus input voltage at TA = 50 C for LOK models operated in vertical position Caution: The installer must ensure that under all operating conditions TC remains within the limits that are stated in the table Temperature specifications. Output Protection 05155a Po allowed /Po nom 1.0 Battery charger versions LOK4140-, 4240-, LOK4740-2RLD, and the LOK4001-2RLD have a rectangular current limitation characteristic, which limits the output current to within 100 and 150% of Io nom. The other models are protected against overload by a current limiting circuit, which shuts down the converter in overload condition. It automatically restarts after removal of the overload condition (hiccup mode). All models are short-circuit and no-load proof.

The value of the maximum output current to be taken is defined by that unit providing the lowest current limiting value. It should be assured that the outputs do not feed backwards into each other caused by their different rise/fall times at switch-on/off cycles by adding reverse polarity diodes across each output. Parallel Operation Only possible with battery charger versions. The outputs of several battery charger models with equal output voltage (e.g. several LOK4240-2RLD) may be connected in parallel.

If the R pin is left opencircuit, the output voltage is set to Vo nom. (see: Output data) The R input is referenced to the secondary side of the converter. Adjustment of the output voltage is possible by means of either an external resistor or a voltage source. b) Adjustment by means of an external voltage Vext between Vo- and R terminal to achieve an output voltage adjustment range of approx. 90 - 110% Vo nom (LOK 4301, 4601 and 4801 types), 93 - 117% Vo nom for battery chargers. Vo * 2.5 V Vext --------- Vo nom Attempting to adjust the output below this range will cause the converter to shut down (hiccup mode).

For optimum battery charging and extended life time of the battery an external temperature sensor may be connected to the R-input. The sensor should be mounted as close as possible to one of the poles of the battery. Depending upon the cell voltage and the temperature coefficient of the battery, different temperature sensors are available.

For mechanical positions of the terminals see Mechanical Data. Connection to the system shall be according to Terminal allocation and Mechanical Data.

These converters are components, intended exclusively for inclusion within other equipment by an industrial assembly operation or by professional installers. Installation must strictly follow the national safety regulations in compliance with the enclosure, mounting, creepage, clearance, casualty, markings and segregation requirements of the end-use application. L Ensure that a converter failure (e.g. by an internal short-circuit) does not result in a hazardous condition. See also Safety of operator accessible output circuit. The phase input (L ) is internally fused by a 1.6 A slowblow type. It is not customer-accessible. This fuse is designed to protect the unit in case of overcurrent. Option F or external fuses in the wiring to one or both input lines (L and/or N ) may therefore be necessary to ensure compliance with local requirements. A second fuse in the wiring to the terminal N is needed if: Standards and Approvals All LOK models are approved according to the standards IEC/ EN 60950-1 and UL/CSA 60950-1. LOR and LOS models are UL 508-listed components and approved to EN 60950:2000 and UL/CSA 60950-1. * Local requirements demand an individual fuse in each source line * Neutral and earth impedance is high or undefined * Phase and neutral of the mains are not defined or cannot be assigned to the corresponding termials (L to phase and N to neutral). Note: Do not open the converters, or guarantee will be invalidated. These converters have been evaluated for: * Class I equipment. * Building in with vertical mounting on a DIN-rail. * Double or reinforced insulation or an earthed part between input and output. * Basic insulation between input and earth * Functional insulation between output and earth * The use in a pollution degree 2 environment * Connecting the input to a primary circuit with overvoltage category II. The converters are subject to manufacturing surveillance in accordance with the above mentioned standards. For details see the Declaration of Conformity (last 2 pages). Protection Degree Make sure that there is sufficient air flow available for convection cooling. This should be verified by measuring the case temperature when the unit is installed and operated in the end-use application. The maximum specified case temperature TC max shall not be exceeded. Note: The converters are designed for vertical mounting on a DIN-rail. If a converter is operated as well in a horizontal position, the measuring point TC should be located on the top. Isolation The electric strength test is performed in the factory as routine test in accordance with EN 50116 and IEC/EN 60950 and should not be repeated in the field. Power-One will not honor any warranty claims resulting from electric strength field tests. Caution: Testing by applying AC voltages will result in high and dangerous leakage currents flowing through the Y-capacitors (see fig. Block diagram). IP 20: All models.

Option K: System Connectors For installation into systems using preassembled harnesses the converters are available with connectors fitted with screw terminals. The system connectors are UL-listed and approved for currents up to 10 A. Wire cross-sections: Solid wires 1.5 mm2 (AWG14), stranded wires 1 mm2 (AWG16).

Conformity with the directive is presumed by conformity wih the following harmonized standards: * EN 61204: 1995 (= IEC 61204: 1993, modified) Low-voltage power supply devices, DC output - Perfomance characteristics and safety requirements * EN 60950: 2000 (= IEC 60950: 1999) for LOS/LOR models EN 60950-1: 2001 (= IEC 60950-1: 2001) for LOK models Safety of information technology equipment. The installation instructions given in the corresponding data sheet describe correct installation leading to the presumption of conformity of the end product with the LVD. All these regulators are components intended exclusively for inclusion within other equipment by an industrial assembly operation or by professional installers. They must not be operated as stand alone products. Hence conformity with the Electromagnetic Compatibility Directive 89/336/EEC (EMC Directive) needs not to be declared. Nevertheless, guidance is provided in most product application notes on how conformity of the end product with the indicated EMC standards under the responsibility of the installer can be achieved, from which conformity with the EMC directive can be presumed.
