Product introduction

Step into the future of electrical efficiency with our magnificent Premium 100VA Control Transformer. This powerhouse is meticulously crafted to cater to the intricate demands of modern machine tools and sophisticated mechanical equipment. Perfectly suited for circuits requiring input voltages of up to 1000V and operating at AC frequencies of 50-60Hz, this transformer is a beacon of reliability and power. It not only endures continuous operation at its rated capacity but excels in energizing general electrical appliances, local illumination, and providing steadfast indicating power with a formidable capacity reaching up to 50000VA.
· Precisely designed to deliver optimal performance at altitudes of up to 2000 meters, ensuring robust functionality in diverse terrains;
· Seamlessly operates within a vast ambient air temperature spectrum from -25ºC to +40ºC. It maintains a 24-hour average temperature that never exceeds +35ºC, guaranteeing smooth, consistent operation without interruptions.
· Unwavering efficiency is maintained with relative air humidity not surpassing 90% at +25°C and kept under 50% at +40°C, ensuring steadfast performance even under varying atmospheric conditions.
· Constructed for environments devoid of violent vibrations and shocks, our transformers are securely protected against rain or snow infiltration, delivering reliable and continuous operation at all times.
Elegantly engineered for use in non-explosive environments, our transformers are safeguarded against the presence of corrosive gases and conductive dust, thereby preserving metal integrity and insulation, ensuring both safety and durability over time.
With designs meticulously tailored to meet an array of capacity, voltage, and application needs, our transformers exhibit diverse structures. They are typically classified into shell-encased and open-frame formats, each expertly designed for specific applications.
Our transformer coils are precision-engineered, whether double-winding or multi-winding, permitting the secondary side to utilize multiple taps or windings. This ensures the precise voltage and capacity distribution necessary for any application.
Our double winding transformer coil operates with remarkable efficiency. The primary current is precisely calculated as I1=Pe/U1, while the secondary current is denoted as I2=Pe/U2, guaranteeing optimal energy conversion and distribution.
