SAFETY DANGER HIGH VOLTAGE RISK OF ELECTROCUTION Observe extreme caution when working with this equipment High voltage power supplies must always be connected to protective earth Do not touch connections unless equipment is turned off and the capacitance of both the load and power supply are grounded Allow adequate time for discharge of internal capacitance of the power supply...
Unit Description The XMPF10N5/24 unit consists of one chassis containing the high voltage power supply. The dimensions are 185mm x 105mm x 33.5mm The unit is designed for operation from 24Vdc ± 10%. The maximum rated input current is 2A. The unit provides an HV Cathode output rated at 10kV, 10W.
Environmental conditions Operating Protection: The power supply will be designed to meet IP40 and will be reasonably protected against dust. Temperature: +5C to +40C. Relative Humidity: 20% to 80% (no condensation) Storage Temperature: -40C to +70C. Relative humidity: 5% to 95% Absolute humidity: maximum 25 gm ³...
Initial Inspection Inspect the package exterior for evidence of damage due to handling in transit. Notify the carrier and Spellman immediately if damage is evident. Do not destroy or remove any of the packing material used in a damaged shipment.
Input and Output Connections Monitoring and Control 7.1.1 HV enable This is a digital input which controls the HV output. Driving this input low (< 0.8V) will cause the HV output to be enabled and ramp up to its programmed value. The filament current will start to ramp up after the high voltage has reached its programmed value, approximately 3 seconds after the HV output is enabled.

Pin connections The low voltage signal connections are made by a 15 way ‘D’ connector; the pin out is shown below: Pin # Signal Name Range +24V input Power Ground Preheat (set value) 0 – 5V from internal pre set Test (Filament Current Direct Program) Do not connect HV enable...
Set Up & Adjustments Connect 24V power to the unit, +24V (pin 1), 0V (pin 2), do not Enable the unit. Connect a multi-meter to pin 15 with return to pin 14. Turn Filament Current Limit adjustment potentiometer on the case side to set a safe value for the maximum filament current.
