3W DC-DC High Voltage Power Supplies
Spellman’s MS Modules have been designed for printed circuit board mounting with high reliability, small size and light weight. The MS 3W modules provide well regulated, low ripple, high stability output voltages ranging from 300V to 3kV in a versatile, compact and cost-effective design. The modules incorporate remote control and arc & short-circuit protection. Radiated pickup is eliminated by sealing each module in an aluminum enclosure.
