Applications
NHR’s programmable DC electronic loads are ideal for medium-to-high-power testing in all markets.
The DC electronic loads (4700/4760) can be used as part of an automatic test station or as a stand-alone, bench-top set-up. The high-voltage DC Electronic Load (4760) is designed for testing applications that require high-voltage (up to 600V) and an exceptionally wide range of measurements, including product dynamic performance. Typical applications include the testing of power conversion/storage products such as DC converters, DC power supplies, fuel cells and batteries, and telecom rectifiers.
The DC Electronic Load (4700) is a relatively low-voltage load (120V) with high-current capability.
