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.
· Perfectly tailored for environments where the altitude does not exceed 2000 meters, ensuring optimal and uninterrupted performance.
· Meticulously engineered to function seamlessly in ambient air temperatures ranging from a brisk -25ºC to a comfortable +40ºC, while maintaining a 24-hour average that never surpasses +35ºC, ensuring consistent and reliable operation.
· Expertly crafted to thrive in conditions where air relative humidity is below 90% at +25°C and remains under 50% at +40°C, preserving performance integrity.
· Constructed to endure environments free from violent vibrations or shocks, with added safeguards against rain or snow exposure, promising longevity and durability.
Meticulously crafted to be safely employed in environments devoid of explosion hazards, with assurances against the presence of corrosive gases or conductive dust that might damage metals or compromise insulation integrity, thereby safeguarding your applications.
Our transformers are custom-designed to meet 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.
