Features

• This device is an AC power backup unit used when the control power supply of the digital multi-relay DMR-Pro is AC power (AC100/110V).
• In systems where control power is sourced internally, this device, when used with the DMR-Pro, allows the protective relay function to continue operating normally for over one second even during AC power drops or outages caused by short circuits or failures.
• Only one DMR-Pro can be connected per unit.
