Product introduction

Introducing our Remarkable 220V Control Transformer, a true marvel of superior engineering craftsmanship. With an astounding capacity of up to 50,000VA, this expertly crafted transformer accommodates input voltages as high as 1000V within AC 50-60Hz circuits. Engineered to perfection, it guarantees flawless operation even under the most demanding conditions. Its unparalleled versatility makes it an ideal choice as a reliable control power supply for a wide range of machine tools and mechanical equipment. From general electrical appliances to localized lighting solutions and indicator power sources, our 220V Control Transformer is your steadfast choice, ensuring dependable performance in every application, every time.
· Perfectly suited for environments where altitude does not exceed 2000 meters, ensuring uncompromised performance.
· Expertly designed to function effectively in ambient air temperatures ranging from -25ºC to +40ºC, while maintaining a 24-hour average that never exceeds +35ºC, ensuring consistent reliability.
· Engineered to excel in conditions where the air relative humidity is below 90% at +25°C, and under 50% at +40°C, maintaining exceptional performance integrity.
· Constructed to withstand environments free from violent vibrations or shocks, with added protection against rain or snow exposure, ensuring robustness and durability.
Meticulously crafted for environments free from explosion hazards, with guaranteed protection against the presence of corrosive gases or conductive dust that could compromise metal integrity or insulation, safeguarding your applications.
Our transformers are tailored 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 essential for a broad spectrum 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 precise voltage and capacity distribution, perfectly tailored to meet your specific requirements.
The calculation for the double-winding transformer coil is as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, providing crystal-clear electrical performance insights.
