Product Features

This series of three-phase dry-type isolation transformers is designed and manufactured in strict accordance with North American standards including UL 1561, CUL, NEC and ANSI C57.12. It is compatible with 60Hz / 50Hz power grid systems. It supports Delta-Wye voltage conversion and neutral point grounding reconstruction, effectively resolving common-mode interference, N-PE interference and grounding issues. Equipped with an electrostatic shielding structure, it delivers excellent resistance to high-frequency pulses and noise coupling. It features reliable dielectric strength without breakdown and stable electrical isolation for precision equipment.

Adopting high-permeability silicon steel sheets, UL-certified flame-retardant insulation materials and Class H insulation system, it applies non-linear winding, optimized coil layout and Vacuum Pressure Impregnation (VPI) process. It offers high efficiency, low loss, low noise, low temperature rise and strong short-circuit resistance.

Application Fields

It meets the requirements for long-term stable operation in North American industrial automation, data centers, medical equipment, photovoltaic inverter systems and imported equipment supporting scenarios. Multiple protection ratings are available: IP20 / IP23 / NEMA1 / 3R. Safe, eco-friendly and maintenance-free, it fully complies with strict safety and energy efficiency requirements of the North American market. Customizable capacity: 10kVA ~ 3000kVA.
