Product introduction

Introducing our extraordinary 220V Control Transformer, a marvel of superior engineering! With an impressive capacity of up to 50,000VA, this expertly crafted transformer effortlessly accommodates input voltages soaring to 1000V within AC 50-60Hz circuits. Its design ensures flawless operation even under demanding conditions. Renowned for its versatility, this transformer is the reliable choice for a vast array of machine tools and mechanical equipment. Whether powering general electrical appliances, serving localized lighting needs, or acting as an indicator power source, our 220V Control Transformer delivers unwavering performance, ensuring dependable results across every application.
· Perfectly suited for use in environments where the altitude does not exceed 2000 meters, ensuring optimal performance and reliability.
· Meticulously engineered to function effectively in ambient air temperatures ranging from a brisk -25ºC to a comfortable +40ºC, with a 24-hour average not exceeding +35ºC, guaranteeing stable and consistent reliability.
· Designed to excel in conditions where air relative humidity is maintained below 90% at +25°C, and under 50% at +40°C, ensuring the transformer maintains performance integrity.
· Constructed to endure environments that are free from violent vibrations or shocks, coupled with protection against exposure to rain or snow, ensuring longevity and durability.
Meticulously crafted for safe use in environments free of explosion hazards, with guarantees against gases or conductive dust that could corrode metals or compromise insulation, safeguarding your applications.
Our transformers are designed to meet a wide range of capacity, voltage, and application requirements, available in various structural designs. Typically offered in encapsulated and open-shell configurations, they provide the adaptability and steadfast reliability demanded by diverse applications.
Featuring transformer coils with double or multiple windings, each unit is equipped with secondary windings that include multiple taps or independent coils, ensuring precise voltage and capacity distribution, accurately tailored to your specific needs.
The double-winding transformer coil calculation is represented as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, providing precise electrical performance insights.
