The 4700 Series Electronic Loads are designed for a wide variety of electronic loading from either within an automatic test station or as a stand-alone, bench-top set up. The Loads are particularly well suited for testing applications that require a full current at low voltages fast-transient simulation capability and comprehensive internal measurements.
The 4700 can be operated manually through the large, touch-panel-enabled GUI or automatically through a remote controller and any number standard test programming languages. Typical applications include the testing of power conversion/storage products such as DC power supplies, telecom rectifiers and batteries.

| 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 DC Electronic Load (4700) is a relatively low-voltage (120V) with high current capability.
The High Current DC Electronic Load (4700 Series) is used in a wide variety of applications that involve automated testing of power conversion device outputs to simulate real-world loading conditions. This DC Electronic Load is ideal for testing applications that require a full current at low voltages, fast-transient simulation capability and comprehensive measurements.
Typical applications include the testing of power conversion/storage products such as DC converters, DC power supplies, fuel cells and batteries, and telecom rectifiers

Notes:
To order an instrument with a touch panel include a -TP after the model number. For Example: 4700-6-TP
The above specifications show typical configurations
¹ Accuracies apply at 23° ±5°C after a 10 minute warm up.
² Current linearly reduced between 1 & 0.15V.
