Programmable DC Electronic Loads - 8500B Series

The 8500B Series programmable DC electronic loads improve upon all aspects of its predecessor while maintaining dependability at a value price. This series supports both SCPI and the backwards compatible legacy protocol.

With a transient mode speed of up to 10 kHz and multi-type input terminals for banana plug or spade connectors, these DC loads are suitable for testing and evaluating DC power supplies, DC-DC converters, batteries, battery chargers, and photovoltaic arrays.
