Product introduction

Unlock the future of efficiency and adaptability with our cutting-edge Premium 100VA Control Transformer. Expertly crafted to fulfill the high standards of contemporary machine tools and mechanical systems, this transformer is perfect for circuits that demand input voltages of 1000V and below, seamlessly operating at AC 50-60Hz. Empowering continuous performance at its rated capacity, it effortlessly energizes general electrical devices, supports local lighting, and delivers dependable indicating power with an extraordinary capacity reaching up to 50000VA.
· Specifically engineered to maintain peak performance in altitudes reaching up to 2000 meters;
· Excels within an expansive ambient air temperature range from a chilly -25ºC to a warm +40ºC, ensuring an average temperature does not exceed +35ºC over 24 hours for consistent and flawless operation.
· Ensures optimal functionality with relative air humidity levels not exceeding 90% at +25 °C and staying below 50% at +40 °C, thereby guaranteeing steady performance across diverse environmental conditions.
· Designed for stable environments, free from harsh vibrations and shocks, and protected from rain or snow exposure, providing reliable, uninterrupted service.
Our transformers are meticulously crafted for safe operation in non-explosive media, functioning without the risk of corrosive gases or conductive dust that could compromise metal durability and insulation integrity, thus ensuring long-lasting safety.
Our diverse transformer designs cater to various capacity, voltage, and application needs, showcasing structures typically divided into shell-encased and open-frame forms, each thoughtfully designed to meet specific application requirements.
Our meticulously engineered transformer coils, whether employing double-winding or multi-winding configurations, enable the secondary side to leverage multiple taps or windings to achieve the exact voltage and capacity distribution needed.
The double-winding transformer coil operates with unmatched efficiency, where the primary current is represented as I1=Pe/U1, and the secondary current as I2=Pe/U2, ensuring top-tier energy conversion and effective distribution.
