The 8550 Series DC electronic loads provide many features and capabilities typically found in performance instruments, at a value price. Capable of sinking 350 W in a compact benchtop form factor, this series is well equipped for testing and evaluating power supplies, DC-DC converters, batteries, battery chargers, and photovoltaic arrays.

Configurable list, transient, and automatic test modes offer dynamically changing load conditions for evaluating a variety of DC sources. The dedicated battery discharge mode simplifies battery testing.
