Electronic Load Fundamentals
What is an electronic load? An electronic load is a test instrument designed to sink current and absorb power from a power source. Power supplies and electronic loads are complementary test equipment. The power supply tests electronic circuits under specific sourcing conditions. The electronic load tests energy sources or energy conversion blocks with static or dynamic loading.
Device manufacturers and design engineers use electronic loads to test power devices such as power supplies, DC-DC converters, chargers, adapters, batteries, solar panels, and fuel cells.
