Does an EBDK require a separate power source?
Does an EBDK require a separate power source in order to operate?
No separate power feed is required. The EBDK works solely based on the Normal power sense feed.
The relays on the EBDK are electrically-held, so that when Normal power is lost, the relays close, generating the dry contact closure. When Normal power is restored, the relays open again, putting the EBDK back into Normal mode.
