B&K Precision 8500B Programmable DC Electronic Loads improve upon all aspects of the 8500 series while maintaining dependability and cost-effectiveness. A set of comprehensive functions make B&K Precision 8500B loads a versatile tool for testing and evaluating DC power supplies, DC/DC converters, batteries, battery chargers, and photovoltaic arrays. List mode, transient mode, automatic test mode, and battery test mode offer a variety of test tools for lab or production line applications. Continuously switching and pulsing load conditions put a dynamically changing load on DC sources. Load behavior can be triggered internally, externally, or remotely from the included application software. Contained in a compact benchtop form factor, these programmable DC electronic loads operate in constant current (CC), constant voltage (CV), constant resistance (CR), or constant power (CW) mode. Internal memory allows for 100 sets of user-configurable parameters, such as voltage, current, slew rate, and width for quick system recall.
