CHAPTER 4 OPERATION

The Series 500A/102A/152A/202A is easily controlled through the remote connector on

the input panel of the unit. Only the ENABLE/RESET, V PROGRAM and GND signals

are required for operation. The remaining signals are provided for status monitoring and

fault diagnosis. A schematic diagram showing the suggested interface circuit is shown in

Figure 4-1. This table is for a standard configuration.

PIN SIGNAL NAME I/O DESCRIPTION

1 ENABLE/RESET INPUT A high signal (+10 to 15V) with respect to

ground (pin 14) will enable the power

supply. Latching faults can be cleared by

cycling this switch. Ground or open disables

the supply.

5 V PROGRAM INPUT A 0-10V signal with respect to ground at

this pin programs the output voltage

proportionally form zero to rated output.

7 VPEAK OUTPUT A 0-10V signal with respect to ground

proportional to the peak of the output

charging voltage. Can be used to drive a

meter displaying peak output voltage.

8 V ANALOG OUTPUT 0-10V analog of output charging voltage

waveform.

10 INHIBIT INPUT A +10 TO 15V with respect to ground,

disables the unit. Open or ground allows

operation. This input can be used to disable

charging during HV switch recovery.

9, 11 +15V OUTPUT 15V regulated. Can be used or user

programming applications 20mA max.

14 GND OUTPUT Control circuit return. Also chassis/earth

ground

15 INHIBIT LED OUTPUT Open collector. Indicates that the power

supply is receiving an INHIBIT signal.

13 EOC LED OUTPUT Open collector. Indicates that the power

supply is reaching end-of-charge, i.e. the V

PROGRAM set point.

3, 6 SUMMARY

FAULT LED

OUTPUT Open collector. Indicates an output

overvoltage. Temperature fault or low input

voltage condition.

2 LOAD FAULT OUTPUT Indicates a shorted O/P or a very large load

capacitor.
