LVD21

Low Voltage Disconnects for High Current Applications

InPower’s Model LVD21-100, -150, and -200-60S Series Low Voltage Disconnects automatically disconnect 12-volt loads from the battery when the battery voltage drops below 11.5Vdc for 60 seconds, leaving enough charge for the vehicle to be restarted by removing the power draw on the battery. They are available in 100 Amp, 150 Amp, and 200 Amp capacities (the LVD21-100-60S, LVD21-150-60S, and LVD21-200-60S respectively). Custom time and voltage trip points can be programmed too.
