Common Concerns Answered
Why is the Newmar APS-160 more expensive than basic switches?
The APS-160 offers advanced solid-state technology for a truly seamless, zero-delay transfer between power sources and includes sophisticated circuitry for reliable automatic selection, features not found in basic manual switches or simpler combiners.
Can this unit work with older positive ground systems?
No, the Newmar APS-160 is specifically designed for 6-50 VDC negative ground systems. Compatibility with positive ground systems requires a different type of power management solution.
What if I have a very tight budget for electrical upgrades?
While the APS-160 represents a premium solution for critical systems, budget-conscious users might consider manual transfer switches for less critical loads. However, for essential electronics, the APS-160's reliability justifies its investment.
