Product introduction

Introducing our Remarkable 220V Control Transformer, a marvel of engineering excellence and pinnacle of innovation. With an astounding capacity of up to 50,000VA, this expertly crafted transformer seamlessly accommodates input voltages as high as 1000V within AC 50-60Hz circuits. Its impeccable design ensures smooth and reliable operation, even under the most demanding conditions. Its unrivaled versatility makes it an indispensable control power supply for a wide spectrum of machine tools and mechanical equipment. Whether powering general electrical appliances, providing localized lighting solutions, or serving as an indicator power source, our 220V Control Transformer is your unwavering choice for dependable performance in every application.
· Perfectly suited for environments where the altitude does not exceed 2000 meters, ensuring continuous and reliable performance.
· Impeccably designed to perform effectively in ambient air temperatures ranging from a crisp -25ºC to a warm +40ºC, maintaining a 24-hour average that never exceeds +35ºC, thus ensuring sustained reliability.
· Engineered to excel in conditions where the air relative humidity is maintained below 90% at +25°C and remains under 50% at +40°C, thus safeguarding performance integrity.
· Constructed to endure environments free from violent vibrations or shocks, with enhanced protection against rain or snow exposure, ensuring longevity and durability.
Meticulously engineered for environments devoid of explosion hazards and fortified against gases or conductive dust that could corrode metals or compromise insulation integrity, preserving the safety and reliability of your applications.
Our transformers are custom-built to meet an expansive range of capacity, voltage, and application requirements, offering a variety of structural designs. Available in both encapsulated and open-shell configurations, they provide the adaptability and unwavering reliability essential for a vast array of applications.
Featuring transformer coils with either double or multiple windings, each unit is outfitted with secondary windings that include multiple taps or independent coils, ensuring precise voltage and capacity distribution, seamlessly tailored to meet your exact needs.
The calculation for the double-winding transformer coil is represented as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, delivering precise and accurate electrical performance insights.
