300W-1200W High Voltage Power Supplies

Spellman’s SLM Series of high voltage modules are designed for OEM applications up to 160kV at 1200 watts. Its universal input, small package size and choice of three standard digital interfaces simplifies integrating the SLM into your system design. Models are available in either positive or negative polarity. The SLM is fully arc and short protected. Excellent regulation specifications are provided along with outstanding stability performance.

Typical applications:

Capacitor Charging
HiPot Testing
CRT Testing
Electrostatics
E Beam Systems
CW Lasers
