B&K Precision 8522 DC Electronic Load

Overview

The B&K Precision 8522 is a programmable DC electronic load designed for testing and evaluating a variety of DC power sources, fuel cells, and solar cells. It operates in multiple modes (CC, CV, CR, CP) and can be controlled from the front panel or via USB interface.

With capabilities ranging from ultra-low voltage (0.1 V) to high voltage (500 V) and high current (240 A, 5000 W), the 8522 is ideal for R&D, manufacturing, and service applications requiring comprehensive load simulation.
