5W X-Ray Generator
The XMPF is a modular 10kV @ 5W X-Ray generator designed to drive a floating filament X-Ray tube via closed loop filamentary control of the 0 to 500uA emission current. The floating filament supply is rated at 0 to 0.42 amps @ 3.5Vac. The filament supply features an adjustable 0 to 0.42 amp filament limit.
The high voltage program and emission current program have internal preset capability simplify interfacing to this X-Ray generator. Alternatively, a customer provided 0 to 10Vdc signal can be used to remotely control these two signals. A high voltage monitor signal and emission current monitor signal is provided. Additionally a filament current monitor signal is also provided. A High Voltage Enable input provides control of the high voltage output.

The pre-set potentiometers are accessible through the side of the case.
To pre-set the filament current limit, adjust the potentiometer (indicated "Preset fil max" on the case).
If external programming is not required:
To pre-set the HV, adjust the potentiometer (indicated RV4 on the case) to desired value, and link pins 7 and 8.
To pre-set the emission current, adjust the potentiometer (RV3), and link pins 12 and 13.
