DESCRIPTION

The PC-R302 Series Telephone Ring Generators offer a line of high

performance sine wave ring generators with an advanced constant

output power driving stage. The device is internally controlled by a

unique micro-controller, which enables flexibility in setting both the

output frequency in the range of 15 to 50Hz and output amplitude in

the range of 45 to 86Vrms 1. The internal controller automatically

adjusts and recovers the output amplitude for overload, over-

temperature, and short circuit.

At power connection or start -up by the Inhibit terminal, the device

turns it' output On and Off at the sine wave zero crossing, and

provides an isolated zero crossing synchronization output. The PC-

R302 Series advanced four-quadrant power topology delivers high

efficiency over the entire input voltage range of 36-72Vdc, and

operates at -40°C to +85°C.

Automatic Overload Control

Loads exceeding the maximum rated load by 1% to 20% activate the

Overload Protection. While the Overloa d Protection is active, the ring

generator automatically reduces its output amplitude and raises its

output current limit in order to sustain output power of approximately

30 Watt. The ring generator gradually reduces its output amplitude

from any set nominal amplitude until it reaches 45Vrms 2 for an

unlimited period. For handling overload that requires voltage lower

than 45Vrms, the device reduces its output amplitude to 30Vrms and

remains at this level for duration limited only by the thermal

protection. The device will shut off for a maximum duration of 2

seconds if the output current exceeds approximately 1Arms. While

the output is disabled, the Test output changes to a low logic level.

After a maximum delay of 2 seconds, the ring generator automatically

reverts to normal operation depending on its existing load condition.

This unique procedure ensures continuous service during overload

conditions.

1 The PC-R302-825 offers an extended output voltage control of 50-

95Vrms.

2 The minimum output voltage of the PC-R302 -825 is 50Vrms.

Output Overvoltage Protection

An independent internal protection circuitry shuts down the ring

generator in the event that the output voltage tries to exceed its

defined operating range. This feature allows meeting international

safety standards. The ring generator automatically recovers when the

output voltage returns to its safe operating range. An external

Transient Voltage Suppressor device should be used for external

high voltage transient protection.

Input Under/Over Voltage Protection

The input voltage protection circuitry shuts down the ring generator

when the input voltage is under/over the defined operating range.

The ring generator automatically reverts to normal operation when

the input voltage returns to its defined operating range.

Thermal Protection

An internal thermal protection automatically reduces the ring

generator output power, according to an internally programmed Safe

Operating Area, in the event that the internal temperature exceeds a

preset threshold. The ring generator automatically reverts to full

output power once the internal temperature reduces to the specified

operating temperature range.

Digital On/Off Control

The Inhibit control terminal (pin 7) functions to shut down the output

and reduces the device current consumption to an idling level. TTL

logic levels referenced to the FGND terminal (pin 6) operate the

Inhibi t terminal. When this input is disconnected or tied to a TTL low

level, the output is enabled. A logic high level inhibits the output and

minimizes the device's current consumption to an idling level. Turn

On and Off functions are executed during the outpu t sine wave zero

crossing, improving reliability.

Note that the Inhibit control can be used to generate the ringing

signal's On/Off intervals. Inhibit control eliminates the need for

additional external components in cadence implementation.

Output Amplitude Setting

The PC-R302-925/926 ring generator output amplitudes may be set

to any value in the range of 45Vrms to 86Vrms. The PC-R302-825

ring generator has an extended output amplitude range of 50-

95Vrms. The PC-R302-543 ring generator output amplitude is set to

86Vrms.

The V0 input terminal (pin 10) controls the output amplitude in digital

and analog operation modes. When V0 is set to <1V in reference to

the DGND terminal (pin 12), or shorted to DGND, the output

amplitude is set to its default 75Vrms value. When V0 >4V or V0 is

left open, the output voltage is sets to 86Vrms. When applying to V0

voltage in the range of 1.152V to 3.804V the device changes to its

analog amplitude setting mode, and sets its output amplitude

according to the table below. Any output voltage setting will take

effect only at startup, by power connection or by Inhibit command.

Zero Crossing Synchronization Output

The SYNC output terminal (pin 9) provides a square wave at the ring

generators output frequency and phase. The output is an open

collector referenced to the FGND terminal (pin 6). This output may

provide up to 30V signal level by using an external pull up voltage.

This can be used to synchronize relay switching with output's zero

crossing. When the ring generator shuts down as a result of shorted

output, over-temperature or disconnected input voltage, this output

will revert to a high level.

Output Frequency Setting

The PC-R302-925/926/825 ring generator supports all four popular

output frequencies: 17, 20, 25 and 50Hz. The F0 (pin 8) and F1 (pin

11) input terminals select the device output frequency by TTL logic

levels referenced to the DGND terminal (pin 12). Changes take

effect at startup, by power connection or by Inhibit command

activation. The PC-R302-543 ring generator output frequency is set

to 25Hz.

Other output frequencies, in the range of 15Hz to 50Hz, in 1Hz

resolution may be ordered.

Test Output Signal

The Test output terminal (pin 5), based on an independent internal

circuit, provides an open collector logic high level, referenced to the

FGND terminal (pin 6), to indicate proper functioning of the ring

generator output. A low logic level appears at this terminal when one

of the following occurs: Output Overcurrent, Over Temperature, Vin

Undervoltage/Overvoltage, High Logic Level at the Inhibit Control

Terminal or an Output Overvoltage. While the unit is normally

operated, this output will be at high level. The Test Output Signal can
