| Model K1/112 Isolated Grid Module - Output 1.2kV Isolated to 50kV
Applications:
This power supply uses the proven precision oscillator from the standard 10 watt HP series and is intended to provide X-ray tube grid control up to 1.2kV. The grid can be isolated from ground by up to 50kV, while power input & control remain at ground potential. Higher isolation voltages, and different o/p voltages are also possible; please consult the factory for more details. Options include beam current stabilisation and control when used to drive an extraction grid. |
