Product introduction

Discover the extraordinary efficiency and versatility of our Superior 100VA Control Transformer, designed to cater to the rigorous demands of contemporary machine tools and mechanical equipment. This essential transformer is perfect for electrical circuits with input voltages of up to 1000V, functioning effortlessly at AC 50-60Hz. With the capability to operate continuously at its rated capacity, it ensures seamless power delivery for general electrical appliances, local lighting, and offers dependable indicating power with an astounding capacity reaching up to 50000VA.
· Specifically engineered for optimal performance at altitudes reaching no more than 2000 meters;
· Capable of functioning flawlessly within a wide ambient air temperature range of -25ºC to +40ºC, maintaining a 24-hour average temperature not exceeding +35ºC to ensure smooth and uninterrupted operation.
· Retains high efficiency with a relative air humidity not exceeding 90% at +25 °C and remaining below 50% at +40 °C, guaranteeing dependable performance across diverse environmental conditions.
· Constructed for environments that are free from severe vibration and shock, and protected against rain or snow intrusion, this transformer assures reliable and continuous operation.
Expertly designed for use in non-explosive media, our transformers function without the presence of corrosive gases or conductive dust that might undermine metal integrity and insulation, ensuring safety and durability over time.
Our transformers exhibit designs specifically tailored to meet varying capacity, voltage, and usage requirements. Featuring diverse structures, they are typically categorized into shell-encased and open-frame forms, each meticulously crafted for distinct applications.
Our transformer coils, whether double-winding or multi-winding, are precisely engineered to enable the secondary side to employ multiple taps or windings, achieving precise voltage and capacity distribution tailored to specific needs.
The double winding transformer coil ensures efficient operation, with the primary current represented as I1=Pe/U1 and the secondary current as I2=Pe/U2, guaranteeing optimal energy conversion and distribution across applications.
