NHRR2 - 30 kV / 5 kW

  • COMPACT DESIGN
  • CONSTANT VOLTAGE / CONSTANT CURRENT
    OPERATION WITH AUTOMATIC CROSSOVER
  • ARC DETECTION AND ARC COUNTER
  • OEM CUSTOMIZATION AVAILABLE

 

NDRR switch mode power supplies are available in 10 models with voltage outputs ranging from 150V to 600V. The NDRR series is specially designed for extremely harsh conditions.

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.

Should your application require a larger power, please use the NHRR NHRR 5 kW or 10 kW range.
