The HW series of high voltage modules covers the range from 1kV to 50kV giving 100Watts of output power. Control of the output voltage is by internal potentiometer or by external potentiometer or by an external 10 volt analogue control voltage. Pins 1 to 10 of the 12 pin Molex input connector are pin compatible with both the high precision HP series and the general purpose KS series.
All units are short circuit proof and use high frequency switching techniques, in conjunction with a ferrite step-up transformer to control the output. The units operate from a 24V input and have an efficiency of around 80%.
O/P Current Control is now available as Constant
Current Option

versions of these units.

CURRENT MONITOR ON HW UNITS
|
|
There are two current monitor options available for the HW series.
|
|
Stack Return Current Monitor
Simple lower cost Current Monitor: Current is measured between pin 11 and pin 9 (0 volt)
The current measured includes internal feedback currents used to control the unit. These currents, which are proportional to the output voltage, are 100uA on the HW series.
