Changes to the output voltage can be made using the front panel potentiometer. A 24 V, 1 A rated relay contact can be used for remote monitoring of the power supply status. The relay contacts are closed when the output is above 95% of the set voltage. The output voltage can be turned off and on using the inhibit function. A closed contact or low voltage activates the output, an open circuit or a high voltage inhibits the output. Clearly marked connection points support digital control panel engineering and automated wiring machines.
