Low Core Loss EE80 High Frequency 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.

• High Power & Low Loss: Premium ferrite core combined with multi-strand Litz wire design reduces AC resistance and eddy current losses, supporting high-power topologies up to tens of kW.

• Superior Thermal Performance: Heavy-duty design with optimized spacing and insulation ensures stable heat dissipation under long continuous full-load operation.

• Global Safety Compliance: Recognized with UL/cUL Class B/F insulation systems (E332338) and fully compliant with RoHS and REACH standards.

• Low Leakage Inductance: Precision winding technology guarantees strict inductance consistency, making it perfectly tuned for resonant LLC circuits.

• Custom Lead & Terminal Integration: Pre-wired with heavy-gauge insulated leads and crimped lug terminals for easy, high-current PCB/chassis installation.

The EE80 LLC Transformer is widely deployed in high-power industrial and energy sector devices:

• Electric Vehicle (EV) Charging: Fast DC charging stations, EV Wallbox chargers, and onboard chargers (OBC).

• Industrial Power Supplies: High-power SMPS, DIN-rail systems, and heavy-duty industrial switching converters.
