Spellman SL60

The Spellman SL60 is a compact high voltage power supply engineered for precision B2B applications requiring stable, regulated DC output. It delivers 0 to 60 kV across multiple current-rated models, with proprietary inverter control technology that maintains fault-free operation in transient and arcing environments. Efficiency exceeds 85%, and integrated arc protection—including Arc Quench, Arc Count, and Arc Trip—ensures safe, reliable performance. The unit accepts 115 Vac or 220 Vac input (±10%, 50/60 Hz) and integrates into larger systems rather than operating standalone.
