Product introduction
Our Efficient Grey 220V Control Transformer, with a capacity of up to 50000VA, is the epitome of reliability and efficiency for power management solutions. This versatile transformer is perfectly crafted for input voltages of 1000V and below, operating seamlessly on AC 50-60Hz circuits. Designed for continuous long-term performance at rated capacity, it is extensively employed in machine tools and mechanical equipment, providing steadfast control power supply for general electrical appliances, along with localized lighting and power indication.
· The operational altitude is optimally set at 2000 meters or below;
· The ambient temperature gracefully ranges from a chilly -25ºC to a warm +40ºC, with an average not surpassing +35ºC over any 24-hour period.
· The air's relative humidity is thoughtfully maintained, not exceeding 90% at a comfortable +25ºC, and a lower threshold of 50% at +40ºC.
· The transformer is ideally used in environments free from harsh vibrations and shocks, and it remains protected from rain or snow infiltration.
In environments free from explosion risks, and devoid of gas or conductive dust detrimental enough to corrode metal or compromise insulation integrity.
Transformers are ingeniously designed to meet the specific demands of capacity, voltage, and application. They are generally categorized into two main structural forms: encased (shell) and non-encased.
The transformer coils are meticulously engineered, featuring double-winding or multi-winding configurations. This ensures the secondary windings can provide multiple taps or employ several windings to achieve the desired voltage and capacity for precise distribution.
In a double winding transformer coil, the primary current is calculated as 11=Pe/1, while the secondary current is determined as 12=Pe/U2, ensuring peak performance.
