Product introduction
Introducing our Reliable Grey Three Phase Control Transformer with CNAS Approval - an engineering marvel that harmoniously blends efficiency with reliability. With a capacity of 50,000VA and below, it is perfectly tailored for circuits with an input voltage of 1,000V or less and operates smoothly in AC 50-60Hz environments. Designed to perform tirelessly under rated capacity, it is the ideal choice for machine tools and mechanical equipment, serving as a steadfast control power supply for general electrical appliances, local lighting, and indicators.
· The altitude for optimal functionality does not exceed 2,000 meters, ensuring dependable performance at varying elevations.
· The ambient temperature range for this transformer is carefully engineered to span from -25ºC to +40ºC, with a 24-hour average not surpassing +35ºC, guaranteeing robustness across diverse climates.
· It thrives in environments where the relative humidity of the air is maintained at no more than 90% at +25°C and does not exceed 50% at +40°C, thereby assuring moisture resilience.
· Designed for stability, it functions optimally in locations free from violent vibrations and shock, and where it is sheltered from rain or snow.
Engineered for safety, this transformer operates in mediums devoid of explosion risks, gases, and conductive dust that could corrode metal or impair insulation integrity.
According to specifications in capacity, voltage, and application, transformers vary structurally, typically categorized into shell and shell-less designs to adapt to different operational needs.
Our transformers boast either double-winding or multi-winding coils, utilizing secondary multiple taps or windings to achieve desired voltage and capacity for effective distribution.
The double winding transformer coil operates with a primary current of I = Pe/U and a secondary current of I = Pe/U, ensuring efficient electrical transformation and distribution.
