Product introduction

Presenting our Outstanding 220V Control Transformer, an epitome of engineering excellence and innovation. With an exceptional capacity extending up to 50,000VA, this meticulously engineered transformer supports input voltages rising up to a remarkable 1000V within AC 50-60Hz circuits. Engineered with precision, it ensures impeccable operation even under challenging conditions. Its unparalleled versatility establishes it as a steadfast control power supply for an extensive range of machine tools and mechanical systems. Be it general electrical appliances, localized lighting solutions, or indicator power sources, our 220V Control Transformer emerges as your steadfast option, promising consistent and reliable performance in every scenario.
· Perfectly suited for altitudes up to 2000 meters, ensuring peak performance and reliability.
· Elegantly designed to function seamlessly in ambient temperatures from a crisp -25ºC to a comfortable +40ºC, maintaining a 24-hour average below +35ºC, thus assuring unwavering reliability.
· Developed to thrive in environments with air relative humidity below 90% at +25°C and under 50% at +40°C, ensuring sustained performance integrity.
· Engineered to endure settings free from violent vibrations or shocks, with additional protection against rain or snow, ensuring longevity and robustness.
Expertly crafted for environments devoid of explosion risks, with built-in assurances against gases or conductive dust that might corrode metals or impair insulation, thereby securing your applications.
Our transformers are skillfully tailored to meet diverse capacity, voltage, and application demands, offering a range of structural designs. Commonly available in encapsulated and open-shell configurations, they deliver the adaptability and unyielding reliability essential for various applications.
Incorporating transformer coils with either double or multiple windings, each unit is equipped with secondary windings featuring multiple taps or independent coils. This guarantees precise voltage and capacity distribution, meticulously customized to fulfill your specific requirements.
The computation for the double-winding transformer coil is expressed as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, providing accurate insights into electrical performance.
