The Newmar ERC-12-35 Emergency Relay/Charger switches communications equipment to a standby battery when DC power is lost, then returns it to the power supply when service resumes. During normal operation, it provides a typical 0.1-amp trickle charge to maintain the battery.
- 12V input range: 10.0–14.5 VDC
- Relay rating: 30 amps continuous, 35 amps intermittent
- Battery float voltage is maintained 0.7 volts below the power supply voltage.
- Includes crimp ring lug connectors and six rubber terminal boots.
- Dimensions: 5-1/8 in. x 2-7/8 in. x 3-5/8 in.; weight: 1.15 lbs.
- Mount vertically, horizontally, or upside down. Inputs and outputs are isolated from the mounting bracket, so mounting on a metal surface is acceptable.
- Use direct wiring and select wire gauge according to total run length: #8 AWG for 5 ft., #6 AWG for 10 ft., and #4 AWG for 15–20 ft.
- Keep the relay away from battery gases and other potentially explosive gases. Do not mount it in the same unventilated enclosure as a stored battery.
- If the standby battery is significantly discharged after extended use, a supplemental charger may be needed; the relay's trickle charge may not restore it promptly.
