Newmar ERC-12-15 - Emergency Relay /Charger

Emergency Relay /Charger

The Emergency Relay/Charger is a device for assuring immediate back-up power to communications equipment in the event AC power is temporarily lost to the power supply or the supply fails.

When loss of DC voltage is sensed by the ERC, it employs a fast-acting S.P.D.T. relay to automatically switch the equipment?s DC input over to a standby battery to allow continued operation. When the power supply is returned to service, the ERC disengages the battery and puts the supply back on line to provide DC voltage. While the power supply is operating normally, a small portion of the output current is directed to the battery to trickle-charge and maintain it at full voltage.( Note: Battery float voltage will be maintained at .7 volts lower than power supply voltage)
