Electronic loads are a key tool for testing, development, and validation of power supplies, converters, batteries, and energy storage systems. They enable controlled simulation of real operating loads and precise measurement of the behavior of the device under test under various operating conditions. Compared to passive resistive loads, electronic loads offer significantly higher flexibility, accuracy, and repeatability of measurements.
The portfolio includes programmable electronic loads designed for both laboratory and industrial use. They typically support CC (constant current), CV (constant voltage), CP (constant power), and CR (constant resistance) modes, allowing simulation of a wide range of load scenarios. This makes them ideal for testing power supply stability, transient behavior, and protection functions.
Types of electronic loads and their applications
Depending on the application, users can choose between DC electronic loads, suitable for testing DC power supplies, batteries, and DC/DC converters, and AC or AC/DC loads, which are commonly used for testing mains power supplies, inverters, or UPS systems. A separate category is represented by regenerative electronic loads, which feed energy back into the grid and significantly reduce operating costs during long-term, high-power testing.
Electronic loads are used not only in development laboratories, but also in production, service centers, the automotive industry, energy, research, and education. Thanks to remote control via interfaces such as LAN, USB, or GPIB, they are also well suited for automated test systems and long-duration load testing.
How to choose the right electronic load
When selecting an electronic load, it is important to consider maximum power, current, and voltage ratings, supported operating modes, measurement accuracy, and control capabilities. In many applications, response speed, setting resolution, and the ability to simulate dynamic load changes also play a key role. A properly selected electronic load significantly improves test efficiency and contributes to higher quality end products.
