SEB e-Gun 6–15 kW Switch Mode Power Supplies

SEB-15 15 kW Switching Power Supply


The SEB series e-gun power supply is a high performance switch mode power supply. It operates above 20 kHz and uses the most reliable IGBT switches available. The SEB power supply is designed to optimize e-Gun performance and maximize power supply reliability in any production coating application.

FilChek Filament Check

The FilChek feature is included as standard equipment on each SEB power supply. A momentary switch, it permits quick and convenient testing of the e-Gun evaporation source filament from the front panel of the power supply. Not a simple continuity check, FilChek supplies a measured, dynamic load through the filament to provide an easy-to-use, reliable, true test of filament condition.

Conservative Electrical Design

SEB power supplies are conservatively designed. Each SEB power supply is designed to operate continuously and reliably at full power and maximum load ratings, with enough head room to accommodate the most dynamic operating characteristics and brutal operating conditions. Every power supply is dynamically tested, including repetitive arc testing, prior to shipment.

Dynamic Arc Suppression

SEB power supplies incorporate advanced arc detection and suppression circuits to insure maximum performance with any evaporant material.


Multiple Output

SEB power supplies are designed to power and operate up to three e-Gun evaporation sources either sequentially or simultaneously. Multiple output taps are provided at the rear of each power supply. Each power supply is shipped with one e-Gun control module as standard equipment. An additional "plug in" e-Gun control module is required for each additional e-Gun you may wish to operate.

Low Stored Energy

SEB power supplies maintain excellent output regulation while minimizing the amount of energy available during arc events. This permits fast arc recovery and greatly enhances e-Gun operation, performance, and reliability.

Compatible with Other Evaporation Sources

The SEB power supplies can be used with all Thermionics e-Gun evaporation sources as well as evaporation sources from other manufacturers. Contact our factory for specific applications.
