Power Supply PS1000-A6-24.10
DC-OK Relay Contact
10
DC-OK Relay Contact
This feature monitors the output voltage on the output terminals of a running power supply.
Figure 10.1 DC-OK relay contact behavior
Contact closes
As soon as the output voltage reaches typ. 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.
Switching hysteresis 1V
Contact ratings
Maximal 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A, resistive load
Minimal permissible load: 1mA at 5Vdc
Isolation voltage
See dielectric strength table in chapter 21.
