NHRR 8-10kV / 3-30kW

  • COMPACT DESIGN

  • CONSTANT VOLTAGE / CONSTANT CURRENT
    OPERATION WITH AUTOMATIC CROSSOVER

  • ARC DETECTION, PATENTED ARC-CURRENT LIMITATION AND ARC COUNTER

 

  • UP TO THREE HV-OUTPUTS POSSIBLE

 
The switch mode power supply NHRR is available with three different output ratings with output voltages of 8kV – 10kV. The NHRR series is specially designed for electron beam evaporation processes. This power supplies contain an ARC-counter and a patented ARC-current limitation which limits the output current peaks to five times of the rated current. Parallel operation to increase power and current capabilities is possible for 10kW models.

SPECIFICATION

Input

400Vac ±10%, 50 or 60Hz, three phase
Output3 models from -8kV up to -10kV with output ratings of 3kW, 5kW and 10kW are available.
Analogue I/O-InterfaceVoltage and current are continuously adjustable over 0 – 10 V analogue inputs. Optionally power regulation and control is possible over analogue input.
Digital I/O-InterfaceWith the digital interface the power supply can be enabled and device-specific and process-specific messages are issued.
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% rms. related to nominal voltage
Patented Arc-Current limitationLimits the output current peaks to five times of rated current.
ARC-CounterWith the ARC-Counter a flash-over can be detected and counted.
