  • Model-50-140.jpg 50-140 Vanner Battery Isolator, 180 amp

    Vanner battery isolators are designed to allow dual battery systems to be charged from a battery charging source while preventing one battery from discharging the other. This protects the engine battery from being discharged by an auxiliary battery operation. Silicon Diode and the low voltage Schottky Diode isolators are available in several current ratings.

    50-140 Specs: Silicon 2-leg isolator, 180 amp alt/165 amp per leg, 2.5"H x 4.5"W x 8"D

  • Model-50-140.jpg 51-140 Vanner Battery Isolator, 250 Amp

    51-140 Specs: Schottky 2-leg isolator, 250 amp alt/200 amp per leg, 2.5"H x 4.5"W x 8"D

    Silicon vs. Schottky diodes: as current passes through an isolator, the diode type affects the voltage loss across it. A Schottky diode reduces the loss by one half of a typical silicon diode.
