Modular, Regenerative, Bi-directional DC Sources
NH Research, Inc.'s (NHR) La línea de fuentes de alimentación de CC incluye la regenerativa Fuente de CC bidireccional de alto voltaje (9300), Modular Bi-directional DC Source (9200, 9210), Fuente de CC de alta corriente (9220), DC Grid Simulator (9410)y Fuente de CA / CC HiVAR (9420) serie. NHR's Las fuentes de alimentación de CC son útiles para probar diseños en una amplia gama de voltajes de entrada de CC.
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.
