Load Connection

 Analog Connector

 Load

Program each unit for full load current and 1/2 the load voltage

Connect for remote sensing (optional)

WARNING

FLOATING VOLTAGES MUST NOT EXCEED ±240 VDC NO OUTPUT TERMINAL MAY

BE MORE THAN 240 V FROM CHASSIS GROUND.

External Voltage Control

The setup shown in Figure 4-9 allows an external dc voltage to program the power supply output. A voltage applied to the voltage programming input programs the output voltage and a voltage applied to the current programming input programs the output current. See Figure 4-1 for an explanation of these programming input connections.

Wiring Considerations. The input impedance of the analog input is over 30 kΩ. If the output impedance of your programming source is not negligible with this, programming errors will result. Larger output impedances result in proportionally greater errors.

1Voltage programming source 0 to –4.15V

2Differential current programming source 0 to +6.75 V

3Differential current programming source 0 to –6.75 V

4Current programming source (floating) 0 to 6.75 V

* Maximum Potential between –IP and ↓P is ±15 V
