Remote Monitoring and Status Indicators

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
"Calibration"
Status indicators for thermal shutdown, OVP operation, remote programming and
operating mode are also available through the J3 connector.
