The FluxCap tm is a step-up power supply that accepts nominal 12 volts DC (11 to 14 volts DC)input to 14.7 (but you can order up to 18 volts DC) standard output at 50 or 100 amps. Note that at higher voltages the current drops to 40 and 80 amps respectively. Includes a trigger input. This is a very efficient, cool running, high performance 2 phase switching converter. You can order either the fixed voltage 50 amp, 100 amp, or adjustable voltage 14 to any custom voltage up to 75 volts for use with lab 12 volt high current DC power supplies to achieve higher output voltages.
