B&K Precision 8514B Programmable DC Electronic Load, 1500 W

This 2U model is equipped for benchtop or rack-mount applications and is suitable for testing a wide variety of DC power sources, DC-DC converters, batteries, battery chargers, and photovoltaic arrays.

As with all 8500B Series models, the 8514B also features a list mode, a transient mode, an automatic test mode, and a battery test function, valuable test tools for lab or production line applications. Additionally, unique to the 8514B is the dedicated USB and RS232 interfaces which support both the SCPI and backward compatible 8500 series protocol. 

The 8514B includes improved features such as a faster transient operation speed up to 10 kHz, an adjustable slew rate in CC mode, and high 16-bit measurement resolution (0.1 mV / 1 mA). Additionally, the completely redesigned front panel contains a bright dual-line display that shows both measured input values and set parameters simultaneously, more convenient menu navigation and value editing keys, and new multi-type input terminals supporting banana jack (up to 10 A) or spade type connections. Extensive protection features improve product reliability and include overtemperature, overvoltage, overcurrent overpower, and reverse polarity protection.

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.
