DC Electronic Loads

Modular, High-Current, & High-Voltage DC Electronic Loads

NH Research, Inc’s (NHR) DC electronic loads include the Modular DC Loads (9200), High-Voltage DC Load (9300) series, and 4 Quadrant AC/DC Load (9430) series.

NHR’s Regenerative DC Loads are ideal for high power test applications, with advanced features and over 90% energy efficiency. Power is converted from the UUT back into usable AC power which is precisely matched to and returned to the facility resulting in lower net utility consumption. Bi-directional power flow allows accurate and effective testing of real-world conditions. Operating costs are lowered by reduced consumption and demand charges as well as reducing or eliminating costs associated with installation, operating, and maintaining chillers and air-conditioning systems.

Applications include testing batteries, EV powertrain, propulsion systems, EV fast charging, energy storage systems, micro-grid, fuel cells, and more.

Key Features:

  • Modular and scalable power
  • Regenerative power
  • Fast transients, sub-millisecond pulse
  • Constant loads – CV, CC, CP, CR & in combination
  • Built-in safety features including pre-charge circuit, isolation relays, etc.
  • Battery Emulation Mode
  • Multiple control options: PC control using LabVIEW & IVI drivers
  • CAN, BMS, DAQ options
