DC Sources

Modular, Regenerative, Bi-directional DC Sources

NH Research, Inc.'s (NHR) DC Power Sources line includes the regenerative  High-Voltage Bi-directional DC Source (9300), Modular Bi-directional DC Source (9200, 9210), High Current DC Source (9220), DC Grid Simulator (9410), and HiVAR AC/DC Source (9420) series. NHR's DC power sources are useful for testing designs over a wide range of DC input voltages.

NHR’s DC sources are designed for testing applications in all types of markets. We offer regenerative, bidirectional and AC/DC sources depending on your test requirements and application needs. All of our DC sources provide modular and scalable power, fast response times, advanced measurements, and built-in safety features to ensure high performance, safety and ease of use.

Regenerative bi-directional sources, grid simulators and battery/DC emulators are the engineer’s tool for testing new electric vehicles, DC fast chargers, satellite systems, solar (PV), energy storage, the utility grid, and power management systems. Simulating the bidirectional power flows to and from the grid substantially speeds up testing time and reduces energy costs.

Bidirectional DC source applications include testing batteries modules and packs, fuel cells, EV subsystems, battery/DC emulation, EV powertrain, propulsion systems, EV charging, energy storage systems, solar PV/wind, micro-grid, and power conversion. In addition, we also offer AC/DC sources for applications that require both AC and DC power.

Bi-directional DC Source & Load

NHR’s Regenerative Bi-directional DC Source and Loads are ideal for high power test applications, with advanced features and over 90% energy efficiency. Bi-directional power flow allows accurate and effective testing of real-world conditions. Unlike bidirectional power supplies, our bidirectional DC sources ensure safety with built-in isolation relays, pre-charge circuits and polarity checkers. We give you the best performance with comprehensive test solutions that are reliable and cost-effective.

  • Regenerative discharge (load) > 90%
  • Built-in safety features including isolation relays, pre-charge circuits, polarity checkers, etc.
  • Battery/DC Emulation Mode (battery, powertrain, solar, satellite, ESS)
  • CAN, BMS, DAQ options

NHR’s High Voltage Bi-directional DC Source – 9300 addresses the increasing power levels used in electric vehicle and renewable energy storage industries. It provides a dual power range (up to 600 V, 1200V) and can be scaled up to 2.4 MW in 100 kW building blocks, offering a wide operating envelope with fast transient times.

NHR’s Bi-directional DC Source – 9200 is ideal for DC power testing where maximum test configuration flexibility is needed to cover a broad range of voltage, current and power requirements. It includes expandable power ranges from 12kW modules up to 252 kW with 40,120 or 600V.
