Redundancy Power Supply - 24V, 10 A, 240 W, Single-phase Input
DC OK Relay Contact
This feature monitors the output voltage of the power supply in front of the
decoupling device.
Figure 13 - DC OK Relay Contact Behavior
Contact closes
As soon as the output voltage reaches Typ 22V DC.
Contact opens
As soon as the output voltage dips below 22V DC.
Short dips will be extended to a signal length of 100 ms. Dips shorter than 1 ms will be ignored.
Switching 1V
