Product introduction

Introducing our Remarkable 220V Control Transformer, a true testament to superior engineering excellence. This ingeniously crafted transformer boasts a commanding capacity of up to 50,000VA, effortlessly accommodating input voltages soaring as high as 1000V within AC 50-60Hz circuits. Masterfully designed, it guarantees flawless performance even when operating at peak conditions. Its unmatched versatility secures its position as a reliable control power supply for a broad array of machine tools and mechanical equipment. Whether utilized for general electrical appliances, localized lighting solutions, or as an indicator power source, our 220V Control Transformer remains your steadfast choice, delivering exceptional dependability and performance across all applications.
· Perfectly suited for environments where altitude remains below 2000 meters, guaranteeing optimal performance for your needs;
· Meticulously engineered to function effectively in ambient air temperatures ranging from a brisk -25ºC to a cozy +40ºC, consistently maintaining a 24-hour average that never exceeds +35ºC, ensuring unwavering reliability.
· Skillfully crafted to thrive in conditions where air relative humidity is maintained below 90% at +25°C, and drops under 50% at +40°C, preserving performance integrity.
· Constructed to endure environments devoid of violent vibrations or shocks, with additional protection against rain or snow exposure, ensuring extended longevity and durability.
Meticulously crafted for use in environments free from explosion hazards, with assured protection against the presence of corrosive gases or conductive dust that could compromise metal integrity or insulation, safeguarding your applications.
Our transformers are thoughtfully custom-designed to meet a diverse range of capacity, voltage, and application requirements, offering an array of structural designs. Typically available in both encapsulated and open-shell configurations, they deliver the adaptability and steadfast reliability necessary for a wide variety of applications.
Featuring transformer coils with either double or multiple windings, each unit is skillfully equipped with secondary windings that incorporate multiple taps or independent coils, ensuring precise voltage and capacity distribution finely tailored to fulfill 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, offering precise and insightful electrical performance metrics.
