The short duration of the initial pulse keeps the coil current within safe limits. Have used 5V relays on 24V this way. Surely the Kilovac has a pull in time? So we can interrupt the current flow a microsecond after it reaches 50% on its way to exceed coil max voltage of 30V - I think not. My method is a working example with circuit and tested.
