200W, 350W High Voltage Power Supplies

Spellman’s PTV Series of modular high voltage power supplies deliver up to 350W of continuous power. A quasi-resonant inverter design provides over 80% effi­ciency with very fast dynamic response. PTV power supplies incorporate extensive standard features in two power output ranges (200W and 350W) with a wide range of output voltages operating to the most exacting specifications. 

Typical applications:

  • Projection Television 
  • X-ray Systems
  • E-beam Systems
  • Capacitor Charging systems
  • CPT/CRT Testing
