DC Electronic Load
Model 8540
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 a DC load in a small package, it can reliably test a 5 volt
power supply to 30 amps and do it continuously.
The 8540 DC electronic 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’s performance is comparable to most full size bench DC loads, yet
it does the job at half the price and takes up half the space on your bench.
