NewMar NS-12-20 Start guard, 12 volt 20 amp

NEWMAR NS-12-20 NAV START GUARD

DC UPS: StartGuard The abrupt DC system voltage drop that accompanies engine starting can cause communication/navigation electronics to "dump" programmed memory. StartGuard solves this problem by providing supplemental voltage to sensitive electronics while the engine is cranked. It contains a sealed rechargeable battery which is switched on-line to electronics when sensing the starter switch or solenoid is engaged. When the engine is running StartGuard automatically goes off-line and the internal battery is recharged by the alternator. Specifications Input Voltage: 13.8 - 14.8 VDC nominal, 15.5 VDC max.
