Figure 4-5. Remote Voltage Sensing

The maximum voltage available at the power supply output terminals during remote sensing (see Figure 4-6) is 50.5 volts. This allows the sum of the voltage across both load leads to equal 10 volts maximum. For lower output voltages refer to Figure 4-3.

Remote Sense Connections

Remember to turn off the power supply before making or changing any connections on the rear panel terminal blocks. Connect the unit for remote sensing by first disconnecting the straps between sense and load terminals. Then make your connections as shown in Figure 4-5. Connect the sense leads as close to the load as possible. See wire size selection (pages 49 - 50) for information on selection of load lead wire gauge. Best results will be obtained by using the shortest load leads practical. It is recommended that you keep your load leads under 14.7 meters (50 feet) per lead because of inductance effects.
