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.
