DC electronic loads are suitable for testing and characterizing a wide range of DC power sources, such as DC power supplies, batteries, fuel cells, solar cells and other power components. Unlike passive resistive loads, DC electronic loads offer a wide variety of voltage/current ranges and can operate under multiple modes such as constant current (CC), constant voltage (CV), constant power (CW), and constant resistance (CR).
B&K Precision's 8500 family of affordable programmable DC electronic loads consists of a wide selection of models in the 300 W - 5000 W range. Each model shares user-friendly features such as flexible operating modes, high resolution meter and VFD display, built-in transient generator, and list mode functionality for custom programmed dynamic load testing.
Model 8540 was designed for users requiring a basic DC load with a compact form factor at a rock bottom price. The 8540's specifications are similar to the 8500 line, but without the extras such as programming interface, triggering, and the ability to create dynamic test conditions.
