Product introduction

Introducing our Remarkable 220V Control Transformer-a masterpiece of superior engineering. With an astounding capacity of up to 50,000VA, this expertly designed transformer gracefully handles input voltages soaring up to 1000V within AC 50-60Hz circuits. Masterfully crafted, it promises impeccable performance, even under demanding conditions. Its unparalleled versatility makes it an indispensable control power supply for an extensive range of machine tools and mechanical equipment. Whether needed for general electrical appliances, localized lighting solutions, or indicator power sources, our 220V Control Transformer is your steadfast choice, ensuring dependable performance across all applications.
· Perfectly suited for environments where the altitude does not exceed 2000 meters, guaranteeing optimal performance with unwavering reliability;
· Expertly designed to operate effectively in ambient air temperatures ranging from a chilly -25ºC to a comfortable +40ºC. It maintains a 24-hour average that never surpasses +35ºC, ensuring consistent reliability and performance.
· Crafted to excel where air relative humidity stays below 90% at +25°C and remains under 50% at +40°C, ensuring the integrity of performance is maintained flawlessly.
· Engineered to thrive in environments free from violent vibrations or shocks, with robust protection against exposure to rain or snow, ensuring longevity and outstanding durability.
Meticulously crafted for use in environments free of explosion hazards, providing assurance against the presence of corrosive gases or conductive dust that could compromise metals or insulation integrity, safeguarding your applications efficiently.
Our transformers are custom-designed to meet a diverse range of capacity, voltage, and application needs, offering multiple structural designs. Typically available in encapsulated and open-shell configurations, they deliver the adaptability and unwavering reliability essential for a broad spectrum of applications.
Featuring transformer coils with either double or multiple windings, each unit comes equipped with secondary windings that include multiple taps or independent coils. This ensures precise voltage and capacity distribution, meticulously 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 accurate electrical performance insights for precise configuration.
