DC-OK relay contact

This feature monitors the output voltage, which is produced by the power supply itself. It is independent of a back-fed voltage from a unit connected in parallel to the power supply output.

Contact closes

As soon as the output voltage reaches 90% of the adjusted output voltage.

Contact opens

As soon as the output voltage dips more than 10% below the adjusted output voltage.
Short dips will be extended to a signal length of 250ms. Dips shorter than 1ms will be ignored.

Contact re-closes

As soon as the output voltage exceeds 90% of the adjusted voltage.

Contact ratings

 

maximal 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A, resistive load

minimal permissible load 1mA at 5Vdc
