Electric Vehicle (EV) Charging Transformers
As electric vehicle (EV) infrastructure expands, transformers play an essential role in powering EV charging stations. HPS EV charging transformers are designed for Level 1, 2, and 3 charging installations, ensuring seamless power delivery, maximum efficiency, and unmatched reliability.
With advanced dry-type transformer technology tailored to meet the unique demands of EV applications, HPS EV duty transformers are driving the charge toward a greener tomorrow by delivering unparalleled performance and empowering the future of sustainable transportation.
Designed to Resolve Common EV Charging Demands
Harmonic Load Management: Certain EV chargers can introduce high harmonic currents, leading to potential overheating in transformers. HPS K-rated EV Duty transformers effectively mitigate these harmonic challenges, ensuring reliable operation.
Environmental Durability: HPS EV Duty transformers are designed for both indoor and outdoor use, standing up to harsh conditions like rain, sleet, and snow. For areas with severe weather, we recommend a 3R rated enclosure for enhanced protection. In warmer climates, our low-temperature rise options help prevent overheating, ensuring steady performance.
Aesthetic Integration: To meet the aesthetic standards of modern charging infrastructure, HPS offers white enclosures as a standard product offering. Additional color options, including blue, red, green, and stainless steel, are available for seamless integration with other OEM equipment.
