Electronic load is a measuring device used for testing power supplies, converters, batteries, chargers, and other DC voltage sources. It allows a defined current or power to be drawn in a controlled manner, making it possible to verify voltage stability, current capability, and the behavior of the tested system under different operating conditions.
Electronic loads are used in laboratories, electronics service centers, R&D departments, and production test stations. They can be used, among other applications, for testing laboratory power supplies, DC converters, battery packs, power modules, and chargers. Selected models also offer battery testing, automatic test functions, settings memory, remote voltage sensing, and communication with a computer via USB, RS232, or LAN.
When choosing an electronic load, it is worth paying particular attention to maximum power, voltage and current ranges, and available operating modes. Measurement accuracy and resolution, load transition speed, automatic test functions, and available communication interfaces may also be important.
