Product introduction

Introducing our Remarkable 220V Control Transformer, a marvel of superior engineering prowess. With an astounding capacity that reaches up to 50,000VA, this transformer is meticulously designed to handle input voltages that soar up to 1000V within AC 50-60Hz circuits. Masterfully engineered, it assures impeccable performance even when operating at its maximum capacity. Its exceptional versatility firmly establishes it as an indispensable control power supply across a vast array of machine tools and mechanical equipment. Whether it's for general electrical appliances, localized lighting solutions, or indicator power sources, our 220V Control Transformer remains your steadfast choice, delivering unmatched reliability across every application.
· Ideally suited for use in environments where altitude remains below 2000 meters, thereby ensuring optimal and uninterrupted performance at all times;
· Expertly designed to function optimally across ambient air temperatures ranging from a brisk -25ºC to a comfortable +40ºC, all the while maintaining a 24-hour average that never exceeds +35ºC, thereby ensuring unwavering reliability.
· Exemplifies peak performance in conditions where air relative humidity is maintained below 90% at +25°C, and stays under 50% at +40°C, thereby preserving performance integrity.
· Constructed to endure in environments devoid of violent vibrations or shocks, with additional protection against rain or snow exposure, ensuring longevity and robust durability.
Meticulously crafted for deployment in environments free from explosion hazards, with guaranteed protection against gases or conductive dust that might corrode metals or compromise insulation integrity, thereby safeguarding your applications.
Our transformers are meticulously custom-designed to cater to a broad spectrum of capacity, voltage, and application requirements, offering a diverse array of structural designs. Typically available in encapsulated and open-shell configurations, they provide the flexibility and steadfast reliability indispensable for a wide range of applications.
Featuring transformer coils with double or multiple windings, each unit is equipped with secondary windings that incorporate multiple taps or independent coils. This design ensures precise voltage and capacity distribution, perfectly tailored to meet your specific demands with accuracy.
The calculation for the double-winding transformer coil is represented as follows: primary current I1 = Pe/U1, secondary current I2 = Pe/U2, which provides exact electrical performance insights.
