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 from 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

VANALOG

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 for 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

OUTPUT

Open collector. Indicates an output overvoltage.

 

FAULT LED

 

Temperature fault or low input voltage condition.

 

 

 

 

2

LOAD FAULT

OUTPUT

Indicates a shorted O/P or a very large load capacitor.
