EI Core Transformer

Introduction of EI Core Transformer

EI Core Transformer is a traditional transformer with simple structure. Iron core and its parts like frame support, support bracket, iron stand, and so on, are orderly made and mass produced, which becomes the easy standard of manufacturing and has low cost. EI Core Transformer can be widely used in electronic and industrial equipment.

Advantages

Low cost, easy to install, the minimum of output power: 5VA (a lot lower cost contrast to toroidal power transformers), being protected by temperature switch or fuse wire.

Application Field

Audio and video amplifier, AC/AC power supply, Electron, Electronic equipment, Lighting fixtures…
