2.12 Remote Monitoring and Status Indicators
Readback signals for remote monitoring of the output voltage and current are available at
connector J3 on the rear of the unit. A 0-5V (uncalibrated) signal between pins 19 (positive)
and 12 (negative) represents 0-100% of the rated output voltage. A 0-5V (calibrated) signal
between pins 7 (positive) and 12 (negative) represents 0-100% of the rated output current. The
offset and gain of the current readback signal may be adjusted through holes in the cover of the
unit (see Section 4.4 Calibration for location of adjusting holes).
Status indicators for thermal shutdown, OVP operation, remote programming and operating
mode are also available through the J3 connector. The table below lists the various signals, the
J3 connector pins where they are available, the approximate magnitude of the signal (measured
with respect to pin 6 of connector J3) and the source impedance through which the signal is fed.
