The water-cooled switch mode power supplies NHRR are available with output voltages of 2kV/3kV and 5kV. The NHRR power supply series provides 5kW or 10kW and is specially designed for applications which need extreme low arc energy and the full output power over a wide range. Parallel operation to increase power and current capabilities are available as option

SPECIFICATION

Input400Vac ±10%, 50 or 60Hz, tree phase
Output12 models with output voltages of 2kV / 3kV / 5kV and with two different output powers of 5kW / 10kW / 15 and 20kW are available. Each model is available with ei-ther positive, negative, or reversible polarity referring to earth
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.
Voltage RegulationLoad dependent: 0,01% at 100 % load step
input voltage dependent: ± 0,01% within defined input voltage range
Current RegulationLoad dependent: 0,01% at nominal current at each voltage jump
input voltage dependent: ± 0,01% within defined input voltage range
Residual ripple 50% rms. related to nominal voltage smaller ripples are possible depending on arc-energy
