Beschreibung

The BK Precision 8514B programmable DC electronic loads improve upon all aspects of its predecessor while maintaining dependability at a value price. A set of comprehensive functions make these 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. Contained in a compact benchtop form factor, the BK Precision 8514B electronic load 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.  Load behavior can be triggered internally, externally, or remotely from the included application software. In addition to front panel and remote interface control, current values can also be programmed with an analog control signal. The electronic loads can be externally controlled from zero to full scale with a 0 to 10 V input signal. A BNC output is available on the rear for monitoring the current with a 0 to 10 V output signal.
