EI40 (6+6) High Frequency Transformer for High Power SMPS, Inverter & UPS Systems

Performance Specifications
Output Power: Under standard high-frequency scenarios (e.g., 100kHz), the output power generally sits between 150W and 500W. With specialized thermal solutions (such as forced air cooling) and targeted circuit topologies (like push-pull configurations), the maximum power can extend from 400W to 800W.
Operating Frequency: It is extensively integrated into high-frequency circuits spanning 20kHz to 500kHz.
Efficiency: A well-optimized design typically delivers an efficiency level exceeding 95%.
