Product introduction

Introducing our Remarkable 220V Control Transformer, a true testament to superior engineering. With an impressive capacity reaching up to 50,000VA, this expertly designed transformer accommodates input voltages soaring up to 1000V within AC 50-60Hz circuits. Masterfully crafted, it guarantees flawless operation even when pushed to its limits. Its unmatched versatility positions it as a reliable control power supply for a broad spectrum 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 performance in every application.
· Ideal for use in settings where altitude does not exceed 2000 meters, ensuring optimal performance;
· Meticulously designed to operate effectively in ambient air temperatures ranging from a brisk -25ºC to a comfortable +40ºC, while maintaining a 24-hour average that never surpasses +35ºC, guaranteeing consistent reliability.
· Crafted to excel in conditions where air relative humidity is kept below 90% at +25°C, and remains under 50% at +40°C, maintaining performance integrity.
· Built to withstand environments that are free from violent vibrations or shocks, with added protection against rain or snow exposure, ensuring longevity and durability.
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.
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, they provide the adaptability and steadfast reliability necessary for a wide array of applications.
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.
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.
