High Current 280A Toroidal Inductor PFC Choke For 30kW 60kW EV Charging Station
The 280A High-Current PFC Inductor is a heavy-duty magnetic component engineered for high-wattage Power Factor Correction (PFC) stages in the 20kW to 100kW+ power range. Built on a high-capacity toroidal core, this inductor is specifically designed to handle a continuous RMS current of 280 Amperes. By combining advanced Edge-winding (Flat Wire) technology with high-saturation magnetic materials, it provides a stable, low-loss solution for large-scale energy conversion systems, ensuring maximum grid efficiency and minimal harmonic distortion in mission-critical industrial environments.
