The 200 watt range HX series of high voltage modules covers the range from 1kV to 50kV, 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. Pins 1 to 10 of the 12 pin Molex input connector are compatible with both the high precision HP series and the general purpose KS series. Please consult the factory if you require floating heater versions for grounded target 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 24V input and have an efficiency of around 80%.

| INPUT VOLTAGE: |
+24 volt d.c. ±10% at 12A. Negative input terminal common to HV earth return. |
| OUTPUT VOLTAGE: |
See separate table. |
| LINE REGULATION: |
Less than 0.1% of maximum voltage for input changes of 1 volt |
| LOAD REGULATION: |
Less than 0.1% for load changes from 10% to maximum. (Measured at maximum voltage). |
| ON/OFF: |
Unit operates when pin 8 is low (<1.5V). This also resets the trip. |
| OVERLOAD PROTECTION: |
Flashover and short circuit proof. Trip on over current, reset by on/off. |
| TEMPERATURE CO-EFFICIENT: |
300ppm/ °C or better. |
| CONTROL: |
- INTERNAL potentiometer.
- EXTERNAL potentiometer or 10V analogue signal. (0 to +10V gives zero to maximum output, tolerance +2%). Input impedance > 100Kohm.
|
| READOUT: |
Voltage monitor 0 to +10V represents zero to maximum output, source resistance 10 kohm. |
| CURRENT MONITOR: |
Current monitor 0 to +10V 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: |
Meets or exceeds the requirements of EN61010-1. |
