Spellman High Voltage Electronics Corp.’s UMW series modular sheet metal-enclosed converters based on surface-mount technology output 8 to 20 kV. CE-listed and RoHS-compliant, they are available in 60- and 120-W models and measure 203 × 114 × 27 mm. They are encapsulated via a proprietary silicon-based potting material that is more lightweight than epoxy. The converters are arc- and short circuit-protected. Proprietary resonant power conversion topology produces low noise and reduces radiated emissions.
