Gleichstromquellen

Modular, Regenerative, Bi-directional DC Sources

NH Research, Inc.'s (NHR) Die Leitung für Gleichstromquellen enthält die Rückspeisung  Bidirektionale Hochspannungs-Gleichstromquelle (9300), Modular Bi-directional DC Source (9200, 9210), Hochstrom-Gleichstromquelle (9220), DC-Netzsimulator (9410), und HiVAR AC / DC-Quelle (9420) Serie. NHR's Gleichstromquellen eignen sich zum Testen von Designs über einen weiten Bereich von Gleichstromeingangsspannungen.

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.

Key Features:

  • Modular and scalable power
  • Regenerative, Bi-directional DC Power
  • Fast transients, sub-millisecond pulse
  • Built-in advanced measurements, waveform capture & analysis

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
