Applications

There are 2-types of programmable dc electronic loads in this general-purpose, medium-to-high-power electronic load family. The 4700 is a relatively low-voltage DC load (120V) with high-current capability. The high-voltage DC load (4760 Series) is a high-voltage electronic load (600V).

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. Such devices include DC power supplies, telecom rectifiers, and traction batteries.
