Newmar 1-3-70A Isolator 1AIT 3BATT 70AMP

The Newmar 1-3-70A Isolator 1AIT 3BATT 70AMP is a heavy-duty battery isolator designed for tactical vehicles, emergency response units, and expedition platforms that require reliable multi-battery charging. Built for law enforcement and military operators who depend on uninterrupted auxiliary power, this isolator automatically manages charge distribution across three battery banks while preventing parasitic drain and battery discharge when the engine is off.

Its robust construction and proven reliability make it the standard choice for command vehicles, mobile command centers, and off-grid tactical operations. This isolator features a 70-amp capacity, enabling simultaneous charging of three separate battery banks without voltage drops or cross-discharge. The unit automatically isolates the primary starter battery from auxiliary systems, protecting engine starting capability even under extreme draw conditions.

One-input-three-output (1AIT 3BATT) configuration allows operators to prioritize the main vehicle battery while feeding independent circuits for communication equipment, lighting arrays, winches, or tactical systems. Solid-state switching eliminates mechanical relay failures common in field conditions, ensuring consistent performance in harsh environments, extreme temperatures, and prolonged deployment scenarios. Tactical teams, law enforcement fleet managers, and military vehicle operators will find this isolator essential for maintaining operational readiness.
