Remote Voltage Sensing at the Front and Rear Terminals

Remote Voltage Sensing at the Rear Panel

External sense terminals are also available on the back of the power supply that allow the rear output voltages to be sensed at the load, which compensates for impedance losses in the load wiring. The front panel binding posts are paralleled with the rear output terminals.

The rear output terminals accept wires sizes from AWG 22 to AWG 10.

To minimize the possibility of instability on the output, keep load leads as short as possible and bundle or twist the leads tightly together to minimize inductance.

N o t e	For rear local voltage sensing connections, the front shorting bars must be removed
	first and connect the sense wires as shown in Figure 3-3.
