120W High Voltage Power Supplies

Spellman’s AC input PCM Series of 120 watt high voltage power supply modules feature a power factor corrected front end, providing  0.99 power factor along with universal input voltage (85Vac to 265Vac) capabilities. These fixed polarity modules (specify positive or negative at time of order) feature both voltage and current regulation with automatic crossover, making them ideal for sensitive load applications. The robust design of PCM Series along with comprehensive arc and short circuit protection allow opera­tion in the most demanding environments.  

Typical applications:

  • Electrospinning
  • Hipot Testing
  • Detector Arrays
  • Electrophoresis
  • Cable Testing
