AC & DC Power Sources

NH Research, Inc.’s (NHR) AC & DC Power Sources include the Bi-directional DC Source (9200), High-Voltage Bi-directional DC Source (9300), Regenerative Grid Simulator, AC/DC Source (9410), and HiVAR AC Source (9420).

NHR’s AC and DC Source test equipment provides modular and scalable power advanced measurement capability, fast response-times, and multiple layers of safety designed into the product. These AC and DC Sources are designed for high performance, configuration flexibility and ease of use. Each has their own specific set of features suited for specific test requirements and applications across electric vehicles, aerospace and defense, renewable energy, and energy storage industries.

Using test equipment for bi-directional power is becoming increasingly important for simulating real world-conditions associated with the electrification of transportation and renewable energy. Regenerative bi-directional sources, grid simulators and battery 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.

AC source applications include grid simulation/emulation for testing PV inverters and other grid-tied products for compliance to IEEE 1547, UL 1741, and global industry standards as well as military testing over a wide range of voltage and frequency options. DC source applications include testing batteries, battery/DC emulation, EV powertrain, propulsion systems, EV charging, energy storage systems, micro-grid, and more.
