DC-OK relay contact

This function monitors the output voltage generated by the power supply itself. It is independent of a voltage fed back from a unit connected in parallel to the power supply output.

The contact closes

when the output voltage reaches the set output voltage.

The contact opens

when the output voltage drops more than 10% below the set output voltage. Short bursts are extended to a signal length of 250 ms. Drops that are shorter than 1 ms are ignored.

The contact closes again

when the output voltage exceeds 90% of the set voltage.

Contact load capacity

Maximum 60 Vdc 0.3 A, 30 Vdc 1 A, 30 Vac 0.5 A, ohmic load

Minimum permissible load: 1 mA at 5 Vdc

Insulation voltage
