EVA Series

Designed for E Beam Coating Applications
3kW, 6kW and 12kW Power Levels
Remote Analog and Ethernet/RS-232 Interface
Fast, User Configurable Dynamic Arc Intervention
Optional Filament Gun Supply (up to 3 channels)

Certifications & Compliance

Spellman’s new EVA Series is specifically designed for demanding electron beam coating applications. A full featured front panel provides local control, while an extensive analog interface allows remote capability. The included Ethernet and RS-232 digital interfaces simplify integrating the EVA into your system design.

The EVA’s robust IGBT inverter design is inherently fault tolerant. The proprietary low capacitance, low stored energy high voltage output section is ideal for dynamic load and fault conditions encountered in coating applications. Fast arc recovery times (<2ms) minimize process interruptions. Many operational parameters can be configured by the user to suit their particular requirements

An optional filament gun supply is available. The EVA can support one, two or three filament gun supply channels providing unprecedented flexibility and cost effectiveness.
