AC & DC Regenerative Test Equipment

Programmable Power for AC & DC

NH Research, Inc.’s (NHR) Regenerative AC & DC test equipment are designed to assist companies in performing testing while simultaneously improving utility-energy efficiency and reducing operating costs. The AC & DC regenerative line includes the Modular DC Loads (9200, 9210), High Current DC Load (9220), High-Voltage DC Load (9300) series, and the 4 Quadrant AC Load (9430) model.  NHR’s Regenerative Grid Simulator (9410) series is a special bi-directional source that simulates the utility voltage and regenerates power sourced by grid-tied inverters. These products are regenerative, meaning that they convert power from the UUT back into usable AC power which is precisely matched to and returned to the facility resulting in lower net utility consumption. 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.

There are a wide range of applications NHR’s AC & DC regenerative test equipment and test systems are designed to support. A partial list of these applications include: battery testing, chargers, Electric Vehicles (EV), vehicle to grid (V2G), flow batteries, fuel cells, micro-grid testing, super capacitors, and much more!

Key Features:

  • Regenerative, recycles loading power instead of converting it into waste heat
  • Bi-directional DC Source (9200 and 9300 Series)
  • Advanced control features beyond simple settings of voltage, current, & power
  • Simulation of real-world conditions (including transients and parameter adjustment)
  • Built-in waveform digitizer & advanced measurement system
  • Precision measurements with separate voltage/current ranges
  • Eliminates need for additional measurement devices

NHR regenerative test equipment deliver the power, precision and flexibility needed to meet or exceed your test solution needs.
