Product introduction

Engineered for excellence, this transformer boasts a robust capacity of up to 50000VA. It is meticulously designed to thrive under input voltages of up to 1000V and operates seamlessly within AC 50-60Hz circuits. Delivering reliable endurance, it performs impeccably over extended periods under full load. Whether it's powering machine tools or mechanical equipment, this transformer is the quintessential control power source for general electrical applications, local illumination, and indicator power supplies.
· Designed for high-altitude performance, our product excels at elevations up to 2000 meters.
· Built to withstand a broad temperature range, from -25ºC to +40ºC, maintaining peak performance without exceeding an average of +35ºC within any 24-hour period.
· Engineered for humid environments, this device operates optimally with air humidity not surpassing 90% at +25°C and not more than 50% at +40°C.
· Constructed to endure stable conditions, free from severe vibration and shock, and protected from rain and snow intrusion.
Designed for secure environments, this transformer is deployed in spaces without explosion hazards, corrosive gases, or conductive dust that could compromise metal or insulation integrity.
Transformers are crafted with precise attention to capacity, voltage, and specific use cases. They are available in varied structures, typically featuring either an enclosed or open-shell design to suit diverse applications.
Expertly engineered, our transformer coils feature double-winding or multi-winding configurations. This allows the secondary to utilize multiple taps or windings, adeptly delivering the necessary voltage and capacity for efficient distribution.
The double-winding transformer coil is meticulously designed, with primary current denoted as 11=Pe/1 and secondary current as 12=Pe/U2, ensuring precise electrical performance.
