CPS20.241-60

C-Series

The internal capacitor, which supplies the energy for the hold-up time is isolated by a diode to the input voltage. A

short on the input line does not discharge the internal hold-up capacitor.

Voltage

This feature monitors the output voltage, which is produced by the DC/DC converter itself. It is independent of a back-

fed voltage from a unit connected in parallel to the DC/DC converter output.

Contact closes

As soon as the output voltage reaches 22V.

Contact opens

As soon as the output voltage falls below 22V.

Short dips will be extended to a signal length of 100ms. Dips shorter than 1ms will be ignored.
