NHR series NIM标准高压电源

产品详情



DESCRIPTION

       The iseg NHR modules are multi-channel high voltage power supplies in 1/12 NIM standard cassette format. The iseg technology combines ultra precise high voltage generation and measurement in pico amp range.

The NHR series provides up to 4 channels, each with an independent voltage and current control and electronically reversible polarity. The 6 kV channel provides a maximum of versatility:with three electronically switchable HV-generation modes it can supply 4 mA up to voltages of 2 kV, 3 mA up to 4 kV or 2 mA up to 6 kV. Alternatively the NHR can be equipped with cost efficient 2 kV / 6 mA channels with one HV output mode.

Several NHR modules can be daisy-chained by CAN and controlled with a single USB connection or by optional iseg iCS system via Ethernet. The module is made of best components such as 24 bit ADC and 20 bit DAC, an excellent front panel control with TFT display plus comprehensive security features.


  • 4 channels, 2 / 6 kV versions

  • electronically switchable polarity

  • 6 kV channel with switchable HV-modes:up to 2 kv / 4 mA, 4 kV / 3 mA or 6 kV / 2 mA

  • ultra low ripple and noise

  • front panel control with 1.44“ TFT display

  • hardware voltage and current limits, control&measure per channel

  • USB and CAN interface, programmable parameters
