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.
voltage from a unit connected in parallel to the power supply output.
Contact closes
As soon as the output voltage reaches 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 250ms. Dips shorter than 1ms will be ignored.

Contact re-closes
As soon as the output voltage exceeds 90% of the adjusted voltage.

Note: The DC-ok feature requires that the output voltage reaches the nominal (=adjusted) level after turn-on in order to function according
to specification. If this level cannot be achieved, the overload lamp will be on and the DC-ok contact will be open. The overload signal
will only shut off as soon as the adjusted voltage is reached. This is an important condition to consider particularly, if the load is a
battery, the power supply is used in parallel or the power supply is used for N+1 redundant systems.
