20kW High Voltage Power Supply

The Series OL20K is a range of high reliability, high voltage power supply systems designed to meet the rigorous requirements of Ion and Electron beam systems. These high performance switch mode systems are based on a power converter using zero-volt switching. A full bridge of the latest generation of Insulated Gate Bipolar Transistor (IGBT) technology in a fully regulated close-loop system capable of continuously supplying up to 20kW of output power, while maintaining flexible control down to a few hundred watts. These highly reliable, rugged systems comprise two units: a rack mounting or free-standing power converter, through which remote controls are facilitated, and a separate HV unit employing a modular disc construction.  Numerous features are incorporated to ensure system integrity is maintained during adverse operating conditions.

Safety The OL20K high voltage power supplies meet the requirements of the Low Voltage Directive, LVD, 73/23/EEC, by complying with BS EN61010-1:2001 when installed as a component part of other equipment.  It is CE marked accordingly. 
Usage Indoor use only
Installation category II (BS EN61010-1)
Pollution degree 2 (BS EN61010-1)
RoHS The OL20K is currently built to non-RoHS standard.  This unit can, however, be configured to meet the requirements of RoHS where significant customer demand requires it, although please note that this will have an impact on delivery timescales.
Altitude Sea level to 2000 metres (6500 feet)
Protection The units are fully protected against over temperature, over voltage, over current, load arcing and output short circuits.  The ACE system can be installed to give added arc management functionality.
Vibration In accordance with BS EN60068-2-6: 1995
Transport, when contained in the original packaging.
Frequency range: 10Hz to 500Hz
Acceleration: 20 ms/s2 crossover at 58Hz (table C.2)
Displacement: 0.15mm maximum
Test conditions as defined in table A.1
Control The power supply is operated by remote control via the 25-way D-type connector situated on the rear panel of the converter.  Full control and monitoring functions are available by this method.  Application of 0 to 10V to the voltage and current control lines programmes the unit for 0 to 100% of rated output.  Similarly 0 to 10V signals provide monitors of the output voltage and current levels.  HV ON/OFF is obtained by shorting two terminals and status lines are provided by open collector outputs.
