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
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 |
|
|
| programs the output voltage proportionally from zero to |
|
|
| rated output. |
|
|
|
|
7 | VPEAK | OUTPUT | A |
|
|
| the peak of the output charging voltage. Can be used to |
|
|
| drive a meter displaying peak output voltage. |
|
|
|
|
8 | VANALOG | OUTPUT | |
|
|
|
|
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 |
|
|
|
|
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. |
