Product introduction

Introducing our Remarkable 220V Control Transformer, a true testament to superior engineering brilliance. This exceptional transformer boasts an astounding capacity that reaches up to an impressive 50,000VA, designed to adeptly accommodate input voltages soaring as high as 1000V, all within AC 50-60Hz circuits. Expertly crafted, it guarantees flawless operation even when pushed to its absolute limits. Its unparalleled versatility positions it as the unrivaled choice for a dependable control power supply across a broad spectrum of machine tools and mechanical equipment. Whether serving general electrical appliances, localized lighting solutions, or indicator power sources, our 220V Control Transformer stands resolute as your steadfast ally, ensuring dependable and unwavering performance in every conceivable application.
· Ideally suited for use in environments where the altitude does not exceed 2000 meters, ensuring optimal and reliable performance;
· Meticulously engineered 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, thus guaranteeing consistent and reliable performance.
· Crafted to excel in conditions where air relative humidity is maintained below 90% at +25°C, and consistently remains under 50% at +40°C, effectively ensuring performance integrity.
· Robustly built to withstand challenging environments that are free from violent vibrations or shocks, with added protection against exposure to rain or snow, ensuring remarkable longevity and unparalleled durability.
Meticulously crafted for safe use in environments devoid of explosion hazards, with reinforced assurance against the presence of corrosive gases or conductive dust that could compromise metal integrity or insulation reliability, safeguarding your vital applications.
Our transformers are meticulously custom-designed to cater to a diverse range of capacity, voltage, and application needs, offering a variety of thoughtfully engineered structural designs. Typically available in both encapsulated and open-shell configurations, they provide the adaptability and steadfast reliability essential for an extensive array of applications.
Featuring transformer coils with either double or multiple windings, each precision-engineered unit is equipped with secondary windings that include multiple taps or independent coils. This innovation ensures accurate voltage and capacity distribution, perfectly tailored to meet your specific demands, every single time.
The calculation for the double-winding transformer coil is precisely represented as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, offering precise electrical performance insights you can rely on.
