Regenerative AC Load with 4 Quadrant Capability

NHR’s AC Load 4-Quadrant Operation offers regenerative, bi-directional capability, ideal for simulating almost any complex linear or non-linear load as well as full line disturbances at any power factor. This bi-directional capability significantly expands load simulation relative to 2-quadrant AC loads.

The Regenerative AC Load (9430) allows creating the reverse current caused by inductive or capacitive loads (low power factors). Power is sent back to the UUT (source) during part of the AC cycle, and accurately duplicates real-world reactive electrical power flows.

  • High energy efficiency > 90%
  • 8 power ratings
  • Scalable power from 12kW up to 96kW
  • 0-350Vrms, 0-606VL-L multi-phase output
  • CC, CR, CP & CV loading modes
