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. | 
| Contact opens | As soon as the output voltage dips more than 10% below the adjusted output voltage.  | 
| Contact re-closes | As soon as the output voltage exceeds 90% of the adjusted voltage. | 
| Contact ratings 
 | maximal 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A, resistive load | 
| minimal permissible load 1mA at 5Vdc | |
| Isolation voltage | see the dielectric strength table in the chapter “Dielectric strength” |
