4700 Series High Current DC Electronic Loads

120 V Electronic Load with High Current Capability

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 of standard test programming languages. Typical applications include the testing of power conversion/storage products such as DC power supplies, telecom rectifiers and batteries.
