NH Research 9420 series AC Power Source

Programmable AC/DC Source

The 9420 series AC Power Source from NH Research is designed according to the latest development standards. The source is compact, modular and field expandable which is ideal for designing into automated test equipment (ATE) systems. An advanced built-in measurement system further simplifies ATE system design by providing the essential functions of a digital multi-meter, current transducer, power analyzer, and oscilloscope.

HiVAR® technology

The Model 9420 AC Source utilizing HiVAR® technology avoids this VA derating penalty by allowing the source to be specified in true power while providing more than twice the reactive power capability for loads with capacitive or inductive elements

Key features

  • Voltage Range – 175/350VRMS, 200/400VDC
  • 7 models – 8kW/21kVA to 96kW/252kVA
  • Unique configuration flexibility provides for single, split, three-phase operation plus full-power DC
  • HiVAR™ design eliminates derating nominal power due to reactive loads
  • Frequency – 30 to 880Hz
  • High-resolution waveform digitizer & scope display
  • Precision ultra-low current measurements
  • Seamless, constant-power operating envelope
  • Built-in 9” touch-panel user interface for manual control & measurement display
  • Graphical waveform editor for user-defined waveforms
  • High-level line disturbance programming Macros
  • External PC option to host NHR emPower® Test Sequencer
  • Alternate programming in LabVIEW, native SCPI, & other IVI-compliant languages
  • Improved power density results in half the panel height of a traditional AC source
