Re: Pre-Charge Circuit Question

The single resistor is the simplest option but causes a constant, though low, power drain. You could also add a secondary toggle switch to the resistor so you would first put it in circuit, wait a couple seconds and then switch on the main power. Another option would be a complex automated solution with relays and contactors. A relay to connect the pre-charge resistor, a timer delay and then connecting the contactor.
