HX Series

HX Series

200W High Voltage Modules

HX040, HX050

Applications: X-Ray, Lasers, Capacitor charging, Ion Pumps, Ion implantation, Magnetrons

  • 40kV & 50kV
  • High efficiency
  • High frequency switch mode control
  • Internal control or externally programmable
  • Short circuit and flashover proof
  • 24 hour burn in
  • Safety assessed to EN61010-1

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.

Electrical Specification
Unit Type Output Ripple At Full Load
HX040PIS300 2 kV to 40 kV at 5 mA Better than 1% peak to peak, measured with 200pf load capacitance
HX040NIS300 -2kV to -40kV at 5mA
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).
  • INTERNAL potentiometer
  • EXTERNAL potentiometer
  • 10V analogue signal. (0 to +10V gives zero to maximum output, tolerance ±2%).Input impedance nominally
Readout Voltage monitor 0 to +10V represents zero to maximum output, tolerance ±3% (Source resistance 10 kohm).
Current monitor (option)0 to +10V ±7% represents zero to maximum current. (Source resistance 10 kohm).
N.B. Current monitor (supplied as standard) includes the internal feedback current of about 100uA. Precision I monitor (available as an option) removes this current to give a true reading of load current.
Operating Temperature 0 °C to +45 °C
Storage Temperature -35 °C to +85 °C
R.F.I. Choke input filter. Steel case for low radiated magnetic field.
Safety Complies with EN61010 Part

IS = Stack Return Current Monitor
IP = Precision Current Monitor

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.
