Telemark – Tetrode Tube Power Supplies

Telemark tetrode tube electron beam source (ebeam gun) power supplies offer users rugged, time tested technology for powering your electron beam sources. There are specific benefits to tetrode tube technology such as on site serviceability, fast arc-suppression and low ripple. Output up to 20kW is available and multiple source operation (up to 3 sources) makes these power supplies economically attractive. The use of overrated tetrode tubes provides instantaneous arc-down recovery. The air cooled design affords easy installation and the output current regulation is held to 1%. The constant voltage output is user adjustable. When combined with the Telemark Digital Sweep, these ebeam power supplies afford extremely stable beam position and repeatable results. Telemark tetrode tube supplies are rack mountable and free standing (above 6kW) to conserve rack space and support remote placement or the units. The use of separate controllers offers fast support and minimal downtime in the event of failures. Handheld remote control units with voltage and current displays are available.
