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. Use rear panel switches SW1-5
and SW1-6 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
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 J2 connector terminal 1 or to the
chassis. See
monitoring.
