Precharge Resistor 500 ohm 100 watt
Shipping calculated at checkout.
This is a 100 Watt 500Ohm precharge resistor. Used to precharge the input capacitor to a DC-DC converter, controller, inverter, etc. to eliminate the sudden inrush of current. This will decrease the charge current under 1 ampere for almost any size pack eliminating the possibility of damage. Once the caps are charged, which takes just a few seconds, then the power can be applied safely.
