Product Description

Product DescriptionEI Type Single-Phase Transformer    EI type single-phase transformer comes with a high-quality laminated silicon steel sheet core—simple structure, compact size, low loss, high efficiency. It's mainly used for voltage conversion and electrical isolation in single-phase circuits, turning 220V/380V input into various output voltages to fit different power needs. It can effectively stabilize output voltage, cut down grid fluctuation interference, and boost electrical equipment reliability. Widely used in residential buildings, small stores, small industrial equipment, home appliances and precision electronic instruments. It's the core supporting part for low-voltage power distribution and small electrical devices.Specification
