BK Precision 8540 直流电子负载（150W，60V，30A）

The 8540 DC electronic load is a very compact, economically priced instrument that is at home on both the bench and the production floor. Though this is an instrument in a small package, it 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, making it well suited to test a variety of DC power sources. The 8540 performance is comparable to most full size bench DC electronic loads, yet it does the job at half the price and takes up half the space on your bench.
