Product introduction

Introducing our Remarkable 220V Control Transformer, a true testament to superior engineering and innovation. With an impressive capacity reaching up to 50,000VA, this expertly designed transformer is adept at accommodating input voltages soaring up to 1000V within AC 50-60Hz circuits. Masterfully crafted to perfection, it guarantees seamless operation even when pushed to its maximum potential. Its unmatched versatility positions it as an indispensable control power supply for a wide array of machine tools and mechanical equipment. Whether it's for general electrical appliances, localized lighting solutions, or indicator power sources, our 220V Control Transformer stands as your unwavering choice, ensuring dependable and flawless performance in every application.
· Perfectly suited for use in environments where altitude does not exceed 2000 meters, ensuring optimal performance and reliability.
· Meticulously designed to operate effectively in a range of ambient air temperatures, from a brisk -25ºC to a comfortable +40ºC, while maintaining a 24-hour average that never surpasses +35ºC. This guarantees consistent reliability and performance, no matter the conditions.
· Crafted to excel in conditions where air relative humidity is kept below 90% at +25°C, and remains under 50% at +40°C. This ensures the maintenance of performance integrity and operational excellence.
· Constructed to endure environments free from violent vibrations or shocks, with added protection against rain or snow exposure. This ensures the longevity and durability of our transformers.
Meticulously crafted for use in environments devoid of explosion hazards, with assurance against the presence of gases or conductive dust that could corrode metals or undermine insulation integrity, safeguarding your applications and ensuring peace of mind.
Our transformers are custom-designed to cater to a diverse range of capacity, voltage, and application needs, offering a variety of structural designs. Typically available in encapsulated and open-shell configurations, these transformers provide the adaptability and steadfast reliability necessary for a wide array of applications, ensuring they meet your specific requirements with precision.
Featuring transformer coils with either double or multiple windings, each unit is equipped with secondary windings that include multiple taps or independent coils. This ensures accurate voltage and capacity distribution, perfectly tailored to meet your specific demands with exceptional precision and efficiency.
The calculation for the double-winding transformer coil is represented as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, providing precise electrical performance insights and ensuring optimal functionality.
