Applications: X-Ray, Lasers, Capacitor charging, Ion Pumps, Ion implantation, Magnetrons
The 200 watt range HX series of high voltage modules covers the range from 40kV to 50 kV, they are particularly intended for X-ray applications. Control of the output voltage is by internal potentiometer, external potentiometer or by external 10 volt analogue control voltage. Control connections are by a 16 Way Ribbon. Please consult the factory if you require floating heater supplies for grounded target X-ray applications.
All units are short circuit proof and use high frequency pulse width modulated switching techniques, in conjunction with a ferrite step-up transformer to control the output voltage. The units operate from a 24 volt input and have an efficiency of around 80%. Please contact us to discuss special versions of these units.

|HX050PIS300||3 kV to 50 kV at 4 mA|
|HX050NIS300||-3 kV to -50 kV at 4 mA|
|Input Voltage||+24 volt d.c. ±10% at 12A. Negative input terminal common to HV earth return.|
|Line Regulation||Less than 0.1% for input changes of 1 volt.|
|Load Regulation||Less than 0.1% for load changes from 10% to maximum. (Measured at maximum voltage).|
|Overload Protection||Flashover and short circuit proof. Trip on over current, reset by on/off.|
|Temperature Co-Efficient||300ppm/ °C or better. (consult factory for improved temperature coefficients).|
|Readout||Voltage monitor 0 to +10V represents zero to maximum output, tolerance ±3% (Source resistance 10 kohm).

Series Code HX
e.g. 40kV Positive HX with the Stack Return Current Monitor (standard unit) is HX040PIS300
Please note that a constant current version of these units is not available. We expect this option to become available during 2005.
