HiTek Power has introduced the OL10K family of 10kW high voltage power supplies for use in a wide range of ion and electron beam systems. The supply's 3U-high convertor box is one of the smallest in the industry, and an optional active arc management system is particularly useful in ion implanter applications. The OL10K family is mains powered and provides a choice of eight maximum output voltages between 60 and 200kV.

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%/8 hours after 1 hour warm-up.

These highly reliable, rugged systems comprise two units: a rack-mounted or free-standing power convertor, through which remote controls are facilitated; and a separate high voltage unit employing a modular disc construction.

A number of features are incorporated to ensure that system integrity is maintained during adverse operating conditions.

These include continuous primary current monitoring with fast pulse truncation and soft start, extensive thermal monitoring and automatic shutdown on key components, passive output current limiting for instantaneous surge control and independent output overvoltage sensing.

Optionally, HiTek Power's arc count and extinguish (ACE) system can be installed for active arc management.

Full remote control and monitoring is available via a 25-way, D-type connector on the rear panel of the OL10K's convertor unit.

The unit also features a full range of front-panel controls and indicators.
