Product introduction

Introducing our Remarkable 220V Control Transformer, a testament to superior engineering prowess. Boasting an impressive capacity of up to 50,000VA, this expertly crafted transformer handles input voltages soaring up to 1000V within AC 50-60Hz circuits with ease. Its flawless operation, even under demanding conditions, marks it as a paragon of reliability. With unmatched versatility, it serves as a dependable control power supply for an extensive range of machine tools and mechanical equipment. Whether for general electrical appliances, localized lighting, or indicator power sources, our 220V Control Transformer is your steadfast choice, ensuring reliable performance across all applications.
· Ideally suited for environments where altitude does not exceed 2000 meters, guaranteeing optimal performance;
· Meticulously engineered to perform effectively in ambient air temperatures from a brisk -25ºC to a warm +40ºC, always maintaining a 24-hour average below +35ºC for consistent reliability.
· Designed to excel under conditions where air relative humidity remains under 90% at +25°C, and stays below 50% at +40°C, preserving performance integrity.
· Built to endure environments free from violent vibrations or shocks, with additional protection from rain or snow exposure, ensuring lasting durability.
Meticulously crafted for environments devoid of explosion hazards, with assurance against corrosive gases or conductive dust that could compromise metal or insulation integrity, safeguarding your applications.
Our transformers are custom-designed to cater to diverse capacity, voltage, and application needs, offering a spectrum of structural designs. Typically available in encapsulated and open-shell configurations, they provide the adaptability and steadfast reliability essential for a wide array of applications.
Featuring transformer coils with double or multiple windings, each unit is equipped with secondary windings that include multiple taps or independent coils. This ensures precise voltage and capacity distribution, finely tailored to meet your specific demands.
The calculation for the double-winding transformer coil is represented as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, offering precise electrical performance insights.
