8. 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 level.
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 100ms. Dips shorter than 1ms will be ignored.
