       What is a High Voltage (HV) Power Supply?    

       High voltage power supplies are complex power conversion circuits that convert a lower voltage potential to a higher voltage potential. Typical output voltages for high voltage power supplies are 1kV to 360kV, although ranges of 62V to 500kV are offered. Spellman’s range of output power spans from less than a watt to over 200 kilowatts.

        High voltage power supplies can operate from DC or AC input voltages. DC input voltages are economical to use in low power applications (1 watt to 125 watts). Typical DC input voltage are +12Vdc and +24Vdc. AC input high voltage power supplies can operate off a variety of input voltages ranging from 100Vac to 480Vac, single phase or three phase depending upon design. Power factor corrected/universal input high voltage power supplies can operate off 90 to 264Vac with no user intervention required.
