ERC-12-35 Emergency Relay
The emergency relay/charger is a device for providing immediate backup power to communications equipment in case of temporary loss of mains power. the power supply or power supply fails. Additionally, this will allow the power supply to act as a "trickle" battery charger without any additional modifications.
When the ERC detects a loss of DC voltage, it uses a SPDT to fast action. relay to automatically switch the DC input of the equipment to a battery backup to allow continuous operation. When power is returned to service, the ERC disengages the battery and brings power back online to provide DC voltage. While the power supply is operating normally, a small portion of the output current is directed to the battery to slowly charge it and maintain it at full voltage. (RemaNote: The battery float voltage will be maintained at 0.7 volts less than the supply voltage.)
Note: If the power supply fails during an extended period of time, the backup battery may discharge significantly when powering the radio. When power is returned to service, the ERC trickle charge rate may be insufficient to quickly restore full battery charge. In this case, an additional charger may be required to fully charge the battery.
Installation
Select a suitable location as close to the battery as possible where there is no probability of accidental contact and short circuit of the terminals. The ERC can be mounted vertically, horizontally or even upside down, if necessary, without affecting its operation. Two #10 sheet metal or wood screws will be required. Mounting on a metal surface is acceptable.The because the inputs and outputs are isolated from the mounting bracket.
Note: If the battery is stored in an unvented enclosure, users are not recommended to mount the ERC in the same box. As with any relay, it should not be in an area where battery gases or any other potentially explosive gases may be present.
Wiring
The Wiring should be as direct as possible. Make sure the battery terminals are free of corrosion. Determine the correct gauge wire using the information below. Wire length is the total path length (ERC to radio + power to ERC) or (ERC to radio + battery to ERC), whichever is longer.
- Wire length 1 m wire = #8 AWG
- 10 ft wire length = #6 AWG
- 15 ft wire length = #4 AWG
- Length of 20 feet of wire = #4 AWG
Use the connectorsCrimp ring terminal connectors provided to secure wiring to the ERC. Models ERC-12-15 and ERC-24-15 have yellow plastic terminal covers, which must be reinstalled after wiring to prevent accidental short circuit.

Newmar ERC-12-35 Emergency Relay Product Description
ERC-12-35 Emergency Relay
The emergency relay/charger is a device that allows to provide immediate backup power to communications equipment. in the event of temporary loss of mains power or power failure. Additionally, this will allow the power supply to act as a "trickle" battery charger without any additional modifications.
When the ERC detects a loss of DC voltage, it uses a SPDT to fast action. relay to automatically switch the DC input of the equipment to a battery backup to allow continuous operation. When power is returned to service, the ERC disengages the battery and brings power back online to provide DC voltage. While the power supply is operating normally, a small portion of the output current is directed to the battery to slowly charge it and maintain itr at full voltage. (Note: The battery float voltage will be kept 0.7 volts lower than the supply voltage.)
Note: If the power supply is disconnected for an extended period of time, the backup battery may discharge significantly when powering the radio. When power is returned to service, the ERC trickle charge rate may be insufficient to quickly restore full battery charge. In this case, an additional charger may be required to fully charge the battery.
