Automatic Power Selectors

The Automatic Power Selector (APS) is a solid state device which enables installation of a seamless, redundant power system for critical electronic loads. It selects the higher voltage of two independent DC power sources and routes power to the load. Should one source falter or fail, the other will automatically supply the load with no transfer delay, operation continues uninterrupted.

Easy installation, two independent power sources are wired to the APS and routed in a single output to the vital load. Alarm sense wires can be easily attached to input studs providing loss of power source signal. Rugged, rust-proof anodized aluminum case.

The Newmar APS-70 Power Selector (part number 496-2170-0) is a solid-state device designed to create redundant power systems for critical DC electronic loads. It automatically selects the higher voltage from two independent DC power sources and routes it to the connected load. This functionality ensures uninterrupted operation by seamlessly switching to the alternate power source if one fails or falters, with no transfer delay. The APS-70 is suitable for IT environments requiring high availability for essential equipment operating between 6 and 50 VDC, negative ground, with a maximum load of 70 Amps. Its anodized aluminum case offers durability. Installation involves wiring two power sources to the APS and connecting a single output to the vital load. Alarm sense wires can be attached to input studs to signal a loss of power source.
