Product introduction

Our Bk Control Transformer, standing strong with a capacity of up to 50,000VA, is designed for versatile applications where input voltage does not exceed 1000V in AC 50-60Hz circuits. This robust transformer can operate continuously under rated capacity, emerging as an indispensable resource for machine tools and mechanical equipment. It serves as a reliable control power supply for general electrical appliances, localized lighting, and indicator power supply systems.
· Designed for altitudes not exceeding 2000 meters;
· Suitable for ambient temperatures ranging from -25ºC to +40ºC, ensuring that the 24-hour average temperature remains below +35ºC.
· Capable of operating in environments where relative humidity peaks at 90% at +25°C, and does not surpass 50% at +40°C.
· Ideal for stable environments free from violent vibrations and shock impacts, and where there is no exposure to rain or snow.
· Perfectly suited for safe mediums devoid of explosion risks, and free from harmful gases or conductive dust that may corrode metals or damage insulation.
Transformers are designed with varying structures based on capacity, voltage, and specific usage requirements, typically classified into enclosures with or without protective shells.
These transformers feature either double-winding or multi-winding coils. The secondary can utilize multiple taps or windings to provide the exact voltage and capacity needed for distribution.
In our double winding transformer coils, the primary and secondary currents follow the formula: Primary Current I1=Pe/U1, Secondary Current I2=Pe/U2.
