High Efficiency 500W EE55 Ferrite Core High Frequency Power Transformer for SMPS and Inverters

High Efficiency EE55 Ferrite Core High Frequency Power Transformer 500W

Engineered for superior performance in switch-mode power supplies (SMPS) and DC-DC converters, this EE55 high frequency power transformer combines MnZn ferrite core technology with precision winding to deliver up to 95% energy conversion efficiency at 500W rated output.

Key Features

• High Efficiency Design: Utilizing PC40/PC44 grade MnZn ferrite material with low core loss characteristics, minimizing eddy current and hysteresis losses across the 20kHz-200kHz operating range.
• Robust Power Handling: Rated at 500W continuous power, suitable for demanding industrial and commercial power supply applications.
• Wide Frequency Compatibility: Optimized for operation from 20kHz up to 200kHz, supporting both conventional and high-speed switching topologies.
• Custom Windings Available: Input and output voltage configurations can be tailored to your specific design requirements.
• Thermal Stability: Class F (155°C) insulation system ensures reliable operation under elevated temperature conditions.

Applications

• Industrial SMPS (Switch-Mode Power Supplies)
• DC-DC Converter Modules
• Pure Sine Wave Inverters
• Battery Charging Systems
• Renewable Energy Power Electronics
• LED Driver Power Supplies

Quality Assurance

Every transformer undergoes 100% testing including inductance measurement, turns ratio verification, hipot testing (primary-secondary), and thermal cycling before shipment. CE and RoHS certified for global market compliance.
