Power Supply Connection
SD834 Power Supply has native DC-OK Relay.
This relay behaves like below:
**Contact closes: for output voltage > 90% of the adjusted output voltage.
**Contact opens: for output voltage dips > 10% below the adjusted output voltage.
For more details please see attached picture.
Also if you are using Redundant Power Supplies, you have to use SS8xx Power Voting Unit. That unit also has native DC-OK Relay,to monitor DC Power Supply is Ok or not.
Hope it helps.
