DC Electronic Loads
Modular, High-Current, & High-Voltage DC Electronic Loads
NHR’s Regenerative DC Loads are ideal for high power test applications, with advanced features and over 90% energy efficiency. Power is converted from the UUT back into usable AC power which is precisely matched to and returned to the facility resulting in lower net utility consumption. Bi-directional power flow allows accurate and effective testing of real-world conditions. 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.
Applications include testing batteries, EV powertrain, propulsion systems, EV fast charging, energy storage systems, micro-grid, fuel cells, and more.
