The BK Precision 8500B220V Programmable DC Electronic Load, 300W, 150V, 30A improves upon all aspects of its predecessor while maintaining dependability at a value price. A set of comprehensive functions makes this model 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 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. PC software is provided for front panel emulation, generating and executing test sequences, or logging measurement data without the need to write source code. Additionally, this application software integrates with NI Data Dashboard for LabVIEW applications, allowing users to create a custom dashboard on a tablet computer or smart phone to remotely monitor the 8500B.
