HiTek Power has introduced the OLS10K family of 10kW high-voltage power supplies for use in a wide range of ion and electron beam systems and other applications. Two versions are available, both housed within a single 6U 19” rack-mounted chassis. The Series OLS10K has been developed to offer alternatives to the separate chassis of the highly successful Series OL6000, OL8000 and OL10K supplies, resulting in a 40 per cent lower volume than previous supplies, coupled with considerably lower weight and cost. These highly reliable, rugged systems are mains powered and provide a range of maximum output voltages from 1kV to 80kV. A parallel option offers a maximum output power of 20kW.
The greatest size reduction has been achieved in the high-voltage part of the system, where the use of an air insulated stack has made a significant contribution. HiTek Power has invested in sophisticated analysis tools and designed a proprietary high voltage sleeve using reaction injection moulding (RIM) equipment. Along with the reduction in size, these techniques have allowed the final output resistor to have a comparatively high value, reducing component stress and increasing reliability.
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. HiTek Power’s proprietary Arc Count and Extinguish (ACE) system is also incorporated for active arc management.
Full remote control and monitoring is available via a 25-way, D-type connector and an RS232 interface, both fitted as standard. The unit also features a full range of front-panel controls and indicators.
