Product introduction
Our Innovative 100VA 3phase Control Transformer is designed with a capacity of 50000VA and below, perfectly suitable for input voltages of 1000V and below AC 50-60Hz circuits. Crafted to perform tirelessly under rated capacity, this transformer is ideal for use in machine tools and mechanical equipment. It serves as a reliable control power supply for general electrical appliances, local lighting, and indicating power supply, offering superior energy efficiency.
· The altitude does not exceed 2000 meters, ensuring optimal performance at elevated heights;
· The ambient air temperature ranges from a chilly -25ºC to a warm +40ºC, with an average 24-hour value not exceeding +35ºC, maintaining efficiency in diverse climates.
· The relative humidity of the air should not exceed 90% at +25 °C, and should not surpass 50% at +40 °C, maintaining stability in varying moisture conditions.
· Designed for environments free from violent vibrations and shock, and where exposure to rain or snow is non-existent, ensuring durability and longevity.
This transformer is crafted for use in mediums devoid of explosion risk, and free from gases or conductive dust that could corrode metal or compromise insulation integrity.
Transformers are engineered with differing structures based on capacity, voltage, and usage requirements, generally categorized into shell and shell-less forms.
Our transformer coils feature double-winding or multi-winding designs. The secondary utilizes multiple taps or additional windings to achieve the desired voltage and capacity for effective distribution.
For double winding transformer coils, the primary current is calculated as 11=Pe/1, while the secondary current is 12=Pe/U2, ensuring precise and efficient energy conversion.
