Product introduction
Presenting our Reliable 220V Control Transformer, an epitome of engineering excellence with a substantial capacity of up to 50,000VA. Expertly crafted for input voltages reaching as high as 1000V within AC 50-60Hz circuits, this transformer is designed for seamless operation even at peak capacity. Its versatility shines through as it serves as a steadfast control power supply across machine tools and mechanical equipment. Whether for general electrical appliances, localized lighting, or indicator power sources, this transformer is your dependable choice.
· Perfectly suited for environments where the altitude remains below 2000 meters;
· Precision-engineered to function optimally in ambient air temperatures ranging from a chilly -25ºC to a warm +40ºC, while ensuring the 24-hour average does not exceed +35ºC.
· Designed to thrive in conditions where air relative humidity is no more than 90% at +25°C, and stays under 50% at +40°C.
· Constructed to endure environments devoid of violent vibrations or shocks and safeguarded against exposure to rain or snow.
Meticulously engineered for environments free from explosion hazards, with no gases or conductive dust that could corrode metals or compromise insulation integrity.
Our transformers are tailored to meet a wide array of capacity, voltage, and application needs, offering an assortment of structural designs. Typically categorized into encapsulated and open-shell configurations, they provide flexibility and reliability for various applications.
Featuring transformer coils with either double or multiple windings, each unit offers secondary windings equipped with multiple taps or independent coils, thus ensuring precise voltage and capacity distribution to meet your specific requirements.
The mathematical expression for the double-winding transformer coil is as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2.
