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's 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.

Easy to Use:

The BK Precision 8540 DC electronic load (60V/30A/150W) can sink DC current in constant current, constant voltage, and constant resistance modes. Measured values have 10 mV and 1 mA resolution. Shorts can be simulated. Storage is provided for up to *40 groups, with 4 instrument setups per group. The instrument is easy to use and will find many uses for testing DC power supplies, batteries, and DC to DC converters.
