Remote Monitoring of Output Voltage and Current

Remote Monitoring of Output Voltage and Current
Readback The J2 connector on the rear panel provides access to calibrated readback signals for
Signals remote monitoring of the output voltage and current. Rear panel switches SW1-5 and
SW1-6 allow you to select either a 0-5 Vdc or a 0-10 Vdc range for the output. The
readback signal represents 0 to 100% of the power supply's output.
See Table 4.3 for the required J2 connections and switch settings for remote
monitoring of readback signals with 0-5 Vdc or 0-10 Vdc outputs. Use shielded pair
wiring (20 to 24 AWG) and ground the shield to J10 sense connector terminal 1
(return sense) or to the chassis.
