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.

Flexible and Easy Control

The DC electronic loads (4760) can be operated manually through the large touch-panel- enabled GUI or automatically through a remote controller and any number of standard test programming languages.

Create Complex, Fast-Transient Load Profiles

NHR’s DC Electronic Loads (4760) are capable of creating a wide variety of complex dynamic load profiles. Types of profiles include micro-second pulses, multiple pulses of varying width, stepped responses, variable slew rates and even simulating an AC component on the DC waveform.

Modular and Scalable Power

The DC Electronic Loads (4760) are modular and scalable, meaning additional auxiliary modules can be added to create a larger load.
