The NH Research 4760 Series Electronic Loads are designed for testing applications that require high-power and high-voltage plus measurement of UUT dynamic performance. Typical power conversion products to be tested include fuel cell testing, power conversion testing, telecom rectifier testing, Vehicle to Grid (V2G) testing, & more. The Nh Research 4760-6 contains a unique Auto Mode that provides glitchless automatic switching between CR, CC, CV and CP limits.
The NH Research 4760-6 high voltage loads are designed to keep running under just about any condition, even certain internal component failures and eliminate the need for separate external instruments and related switching to capture timing and other dynamic measurements during UUT turn-on and turn-off. To facilitate ease of re-creating complex, precisely timed, multi-mode load profiles, a 100-step macro-recording capability allows capturing a dynamic sequence for later playback from within the Load. Because the NH Research 4760-6 electronic DC loads are modular, synchronously controlled and actively power-balanced, they operate efficiently in parallel as a single load.

| 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.
