Unit Description
The XMPF10N5/24 unit consists of one chassis containing the high voltage power supply.
The dimensions are 170mm x 70mm x 30mm
The unit is designed for operation from 24Vdc ± 10%. The maximum rated input current is 500mA.
The unit provides an HV Cathode output rated at -10kV, 5W. With a floating filament intended to drive an X-
ray tube with a grounded anode, rated at 0V to 3.5Vac referenced to the Cathode Output, 0.42A max.
All control and monitoring is accomplished via
a 15 way ‘D’ connector which also provides input power to the
unit.
Operating Temperature is 5
C to +40
C ambient for normal operation.
The mass of the module is nominally 2kg.

Safety
The HV output of the unit is hazardous and the conditions of this manual must be complied with to maintain
safety. Operating the unit in a manner not specified in this manual may impair the protection against electric
shock provided by the unit.
The unit is contained in an earthed case, the system protective earth shall be provided to the chassis. The
case of the unit shall be properly bonded to the main protective earth termination in the end product.
The unit has been evaluated for use in a Pollution Degree 2, Installation Category II environment.
Consideration should be given to conducting the following tests with the unit installed in the end product:
Dielectric Voltage Withstand Test, between live parts of the unit and the end product chassis.
Permissible Limits Tests with the unit installed in the end product.
Temperatures on power electronic components, transformer windings and accessible surfaces.
There is no relevance to a risk assessment carried out as part of the CE testing on the HV unit. It is
recommended that a full assessment is carried out in the end application.
