Product introduction

Unveiling our Reliable 220V Control Transformer, a powerhouse engineered for excellence with a remarkable capacity reaching up to 50,000VA. Specifically designed for input voltages soaring to 1000V within AC 50-60Hz circuits, this transformer is your go-to solution for continuous operation at peak capacity. Its versatility shines across machine tools and mechanical equipment, providing a steadfast control power supply for a myriad of general electrical appliances, localized lighting, and indicator power sources.
· Perfectly suited for installations where the altitude remains below 2000 meters.
· Skillfully designed to function in ambient air temperatures ranging from a chilly -25ºC to a warm +40ºC, with the 24-hour average temperature not exceeding a comfortable +35ºC.
· Specifically crafted for environments where the air's relative humidity stays below 90% at +25°C, and remains under 50% at +40°C.
· Constructed to endure environments free from harsh vibrations or shocks, and safeguarded against rain or snow exposure.
Purposefully engineered to thrive in environments devoid of explosion risks, ensuring the absence of gases or conductive dust that could corrode metals or compromise the integrity of insulation.
Our transformers are expertly crafted to meet an array of capacity, voltage, and application needs. They are available in a variety of structural designs, predominantly categorized into encapsulated and open-shell configurations, ensuring optimal performance tailored to your specific requirements.
Our innovative transformer coils feature either double or multiple windings. They provide secondary windings with multiple taps or independent coils to achieve the perfect balance of desired voltage and capacity distribution.
The equations governing our double-winding transformer coils are meticulously designed: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, ensuring precise calculations for your specific applications.
