Product Description
1. Product Overview 
Low Core Loss High Frequency EE80 LLC Transformer For EV Wallbox Charging

The EE80 High-Frequency LLC Transformer is engineered for high-power, modern energy conversion systems requiring ultra-high efficiency and superior thermal management. Designed with advanced Litz wire windings and premium-grade ferrite cores, it minimizes skin effect and core losses at high switching frequencies.

Fully certified under UL/cUL safety standards (UL File: E332338), the EE80 series provides a compact, heavy-duty magnetic core solution for global EV charging stations, industrial power units, and solar inverters.
