Robust high voltage power supplies in
rack mounts
The OL20K 20kW family of robust high-voltage power supplies, offers output voltages from 60 to 200kV and beyond.
HiTek Power has added the OL20K 20kW family to its range of inherently robust high voltage power supplies, offering output voltages from 60 to 200kV and beyond The eight members of this family have been built to meet the rigorous requirements of ion beam and electron beam systems

HiTek Power has introduced the TEK PFC Series of low-voltage, switch-mode power supplies in low-profile open-frame or fully enclosed configurations.
In addition to standard units, the supplies can be customised to meet specific requirements.
Each system consists of a convertor, in a 6U, 19in rack-mounting unit, and a separate high-voltage multiplier assembly.
Power conversion is achieved by zero-voltage switching a full bridge of the latest generation insulated gate bipolar transistors (IGBTs).
The system's arc protection is so good that the output can be shorted to ground repeatedly in quick succession, with no damage to the supply.
The supplies are highly stable: output voltage changes by less than 0.1% for a zero to full load change in load current and the output will recover to within +/-0.5% of set value in less than 100ms from the removal of a short circuit.
Ripple is less than 0.1% peak-to-peak of rated output.
The temperature coefficient is less than 200ppm/C and drift is less than 0.5% in 8hr after 1hr warm-up.
A full remote interface incorporates both digital and analogue control and monitor signalling.
All are optically isolated to provide an efficient and versatile power supply.
