Discover the Solutions
An electronic load is a programmable device that simulates real-world load conditions by drawing current or power from a power source. It operates in various modes like constant current (CC), constant voltage (CV), constant power (CP), and constant resistance (CR).
Electronic loads are widely used in power supply manufacturing, battery testing, EV and BMS validation, solar and renewable energy systems, telecom base stations, and data center power systems.
The key modes are constant current (CC), constant voltage (CV), constant power (CP), and constant resistance (CR). Each mode serves different testing purposes based on the DUT’s behavior and requirements.
In CC mode, the electronic load sinks a fixed current regardless of voltage, ideal for battery testing. In CP mode, it adjusts current dynamically to maintain constant power, which is useful for motor or power device testing.
Yes, most modern electronic loads support SCPI or Modbus commands for full integration with ATE systems, enabling remote control, sequencing, and data acquisition in automated testing environments.
Regenerative electronic loads return absorbed energy back to the grid instead of dissipating it as heat. This greatly reduces cooling requirements, lowers operating costs, and supports sustainable laboratory environments.
Electronic loads typically include protections such as over-voltage protection (OVP), over-current protection (OCP), over-power protection (OPP), and short-circuit protection (SCP) to safeguard both the device under test (DUT) and the equipment.
Yes. By switching between load levels at high speed, electronic loads allow engineers to evaluate the dynamic response of power supplies, batteries, and converters, including overshoot, undershoot, and recovery times.
Key factors include maximum voltage, current, and power ratings, minimum operating voltage, accuracy, dynamic response speed, regenerative capability, and available communication interfaces for automation.
