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  | See the table in chapter Dielectric strength  |
