Newmar ERC-12-15 Emergency Relay

The Newmar ERC-12-15 Emergency Relay is a critical backup power management device engineered for vehicles and equipment that depend on uninterrupted communications during power failures. Mechanics and fleet operators rely on this relay to maintain system integrity when AC power is interrupted or the primary power supply fails. Whether you're running diagnostic equipment, onboard communications systems, or sensitive vehicle electronics in a mobile workshop, the ERC-12-15 delivers the failsafe redundancy that prevents downtime and data loss in mission-critical applications.

This emergency relay functions by providing immediate backup charging capabilities to your communications equipment, allowing your primary power supply to continue functioning as a charger even during AC power loss. The 12V/15A rating ensures sufficient capacity for multiple simultaneous loads without voltage sag or performance degradation. The compact 4x4x8 inch form factor and lightweight 0.75 lb construction make it ideal for dash mounting, engine bay installation, or integration into auxiliary power systems where space is premium. The solid-state relay design offers faster switching speeds and higher reliability compared to mechanical alternatives, eliminating contact bounce and wear-related failures common in traditional electromagnetic relays.

Most benefit from the ERC-12-15 includes fleet managers operating mobile service vehicles, emergency response teams, and technicians managing on-board diagnostic or telematics systems that cannot afford communication loss. Installation requires basic 12V DC wiring knowledge—connections are straightforward with clearly marked terminals for AC input, DC output, and battery backup lines. The relay integrates seamlessly with existing Newmar power supplies and is compatible with 12-volt vehicle electrical systems across trucks, commercial vehicles, and stationary emergency equipment. For anyone whose work depends on continuous power delivery, the ERC-12-15 is an essential insurance policy against costly communication failures.
