The BK8540 DC electronic load is a compact, economically priced instrument equally well-suited for use on the bench and the production floor. Although it comes in a small package, the BK8540 can reliably test a 5-volt power supply to 30 amps and do it continuously.

The load can operate in CC, CV or CR mode while voltage/current or resistance/power values are measured and displayed in real time, offering the flexibility to test a variety of DC power sources.

The BK8540 performance is comparable to that of most full-size bench DC electronic loads, but it can do the job at lower cost and takes up less space.
