Newmar NS12-20 - StartGuard DC Power Supply
Maintains Constant Voltage to Electronics During Engine Start
The Start Guard is a specialized engine starting version of Newmar's Nav Pac.
The abrupt DC system voltage drop that accompanies engine starting can cause microprocessor-driven communication and 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 and relay, which switches on-line to electronics when 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.
