Product introduction
Our Reliable 220V Control Transformer boasts a capacity of up to 50,000VA, tailor-made for input voltages of up to 1000V within AC 50-60Hz circuits. Designed to perform continuously even at maximum capacity, this transformer finds its versatile use across machine tools and mechanical equipment, serving as a dependable control power supply for general electrical appliances, localized lighting, and indicator power sources.
· Ideal for locations where the altitude does not exceed 2000 meters;
· Engineered to operate in ambient air temperatures ranging from -25ºC to +40ºC, ensuring that the 24-hour average temperature does not surpass +35ºC.
· Designed for environments with air relative humidity not exceeding 90% at +25°C, and remaining below 50% at +40°C.
· Built to withstand environments free from violent vibrations or shocks, and safe from exposure to rain or snow.
Engineered for environments devoid of explosion risks, ensuring no presence of gases or conductive dust capable of corroding metals or compromising insulation integrity.
Our transformers are crafted to meet diverse capacity, voltage, and application requirements, offering a variety of structural designs, typically categorized into encapsulated and open-shell configurations.
The transformer coils feature either double or multiple windings, providing secondary windings with multiple taps or independent coils to achieve the desired voltage and capacity distribution.
The double-winding transformer coil equations are as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2.
