÷ 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.
1 Voltage programming source 0 to –4.15V
2 Differential current programming source 0 to +6.75 V
3 Differential current programming source 0 to –6.75 V
4 Current programming source (floating) 0 to 6.75 V
* Maximum Potential between –IP and ↓P is ±15 V
