The switch mode power supply consists of two Independent power elements. One of them generates the high voltage, the other the Filament current. Both have a common control-regulation-unit.

The powre supply has an configurable ARC-Management and a patented ARC-current limitation, which Limits the Output current in case of an ARC to the maximum of the five times of the rated output current.
For the Operation and adjustment of the unit an analogue/digital Interface is available. In Addition the unit includes a RS232-interface for the Service.

SPECIFICATION

Input

Power: 400Vac ±10%, 50 or 60Hz, three phase
Regulation: 24VDC
±20%, max. 2A

OutputHigh voltage: -8kV / 250mA/ 2kW
Filament:: 8Vdc / 27,5Adc / 220W
Analogue I/O-InterfaceVoltage and current are continuously adjustable over 0 – 10V analogue inputs. The actual values are issued at the analogue interface with 0 – 10V.
Digital I/O-InterfaceOver the digital interface the power supply can be released as well as device-specific and process specific messages are issued.
RS232-InterfaceWith this interface the set points for the output values could be given and read out. Further more the device could be enabled / disabled, failure messages could be read out and advanced arc management setting could be done.
Voltage RegulationLoad: 0,01% of full voltage for full load change.
Line: ± 0,01% of full voltage over specified input range
Current RegulationLoad: 0,1% of full current for any voltage change
Line:
± 0,1% of full current over specified input range.
Residual ripple 1% eff. related to nominal voltage
Patented Arc-Current limitationLimits the output current peaks to five times of the rated current.
Arc-CounterWith the arc-counter a flash-over can be detected and counted.
