Isolators

NEWMAR 1-2-120A ISOLATOR 1AIT 2BATT 120AMP These heavy duty isolators allow charging multiple batteries automatically from one or two alternators, and prevent discharge or "dumping" of one battery into another. Each battery is charged according to its need without overcharging. Rated for 12-48 volt negative ground DC systems. Feature conservatively rated diodes and a rustproof anodized…

NEWMAR 150-A ALTERNATOR FILTER The interference or electronic "noise" generated by alternators, ignition systems, motors, etc., can render a vehicle or vessel's radio or other electronic equipment virtually useless. This interference takes the form of popping or static on radios or audio gear and garbled images or "hash" on video displays. These specialized filters can be…

NEWMAR GI-30 GALVANIC ISOLATOR Sacrificial zincs corrode away as they protect metal thru hulls, shafts and props from damaging electrolysis. Stray, low voltage current flowing between the AC safety ground and DC bonding system is a principal cause of this "galvanic" action. Installing the Galvanic Isolator between the AC safety ground and DC bonding system (see diagram), blocks a majori…
