8550 Series Programmable DC Electronic Loads

B&K Precision's 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.

Static operating modes include constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CW). Configurable list, transient, and automatic test modes offer dynamically changing load conditions for evaluating a variety of DC sources. Additionally, the dedicated battery discharge mode simplifies battery testing with configurable stop conditions. Load behavior can be triggered internally, externally, or remotely.

Operating and battery test software are provided for remote PC control and monitoring through the RS232 interface. The general purpose handler interface offers pass/fail feedback and simplifies integration with PLC devices, commonly found in production and manufacturing environments. Measurement data and other parameters can be logged directly to a Flash drive connected to the front panel USB host port.
