Product introduction

Presenting our Extraordinary 220V Control Transformer, an epitome of advanced engineering excellence. Boasting a phenomenal capacity reaching up to 50,000VA, this meticulously engineered transformer effortlessly handles input voltages soaring to 1000V within AC 50-60Hz circuits. Expertly constructed, it ensures seamless operation even under maximum load conditions. Its unparalleled versatility makes it the definitive control power supply across a diverse array of machine tools and mechanical equipment. Be it general electrical appliances, specialized lighting solutions, or precise indicator power sources, our 220V Control Transformer is your unyielding choice, promising unmatched performance across all applications.
· Perfectly suited for environments where altitude remains below 2000 meters, ensuring peak performance and reliability;
· Expertly designed to function efficiently in ambient air temperatures stretching from a brisk -25ºC to a warm +40ºC, while sustaining a 24-hour average that never exceeds +35ºC, ensuring unwavering dependability.
· Engineered to perform optimally in conditions where air relative humidity is maintained below 90% at +25°C, and under 50% at +40°C, ensuring the integrity of performance is never compromised.
· Constructed to endure environments free from violent vibrations or shocks, with added resistance to rain or snow exposure, guaranteeing exceptional durability and longevity.
Skillfully crafted for deployment in settings devoid of explosive hazards, and guaranteed protection against gases or conductive dust that could corrode metals or impair insulation, ensuring the safety and reliability of your applications.
Our transformers are ingeniously designed to meet a broad spectrum of capacity, voltage, and application requirements, offering a diverse range of structural designs. Available in both encapsulated and open-shell configurations, they deliver the flexibility and steadfast reliability essential for a wide variety of applications.
Featuring transformer coils with double or multiple windings, each unit is fitted with secondary windings that incorporate multiple taps or independent coils. This ensures precise voltage and capacity distribution, expertly tailored to meet your specific requirements.
The double-winding transformer coil calculation is as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, delivering precise insights into electrical performance.
