Applications

The High-Voltage DC Load (4760 Series) is designed for testing applications that require high-voltage plus an exceptionally wide range of measurements, including product dynamic performance. The electronic loads provide superior reliability derived from the inherent simplicity and safety of air cooling. Automated testing may be PC-controlled either through NH Research’s emPower™ test executive or user-written test programs in LabVIEW, LabWindows/CVI or in any programming language which supports IVI Drivers. Typical power conversion products to be tested include higher-power DC supplies, telecom rectifiers, fuel cells and batteries.
