External Monitoring of Output Voltage and Current
The J1 connector also provides analog signals for monitoring the
output voltage and current. Selection of the voltage range between 0
– 5V or 0 – 10V is made by SW1 setup switch 4. The monitoring
signals represent 0 to 100% of the power supply output voltage and
current rating. The monitor outputs have a 500Ω series output
resistance. Make sure that the sensing circuit has an input resistance
greater than 500 kΩ or the accuracy will be reduced.
