Low Frequency EI Transformers

We manufacture low-frequency EI Transformers of all sizes and designs, ranging from EI 28 to EI 228 and wattage from 0.3VA to 5000VA. All the products use high-quality silicon steel sheet that features low consumption, high output power, high efficiency, low-temperature rise, low noise, and stable performance.

All the EI transformers will go through strict testing to reduce rejection rate before submitting to our clients. Applications of our EI laminated transformers can be found in electronic and electrical equipment such as access control systems, lighting, automatic doors, garage doors, industrial equipment, household appliances, medical devices, inverters, power supplies, UPS, audio equipment, instrument, security system, etc.
