Supplies use arc control for e-beam coating

The EVA series rack-mounted, high voltage power supplies target e-beam coating applications. The supplies are available in 3, 6 and 12-kW versions. They use a rugged IGBT switch mode design to limit stored energy and provide correct regulation and ripple.

The power supplies are tolerant to transient and continuous arcing. With its low stored energy and low capacitance output, the supplies minimize power delivered during arcing events and permit rapid arc recovery times. Arc intervention parameters can be optimized via the unit’s GUI. Adjustable values include arc quench, re-ramp, count, and arc rate limiters.
