Product introduction
With a robust capacity of 50000VA or less, the SBK Series Control Transformer by Dongliang Electric Co., Ltd. is tailor-made for systems with input voltages of 1000V or lower and operates seamlessly within AC circuits of 50-60Hz. Engineered for enduring performance, it can sustain continuous operation at its rated capacity. This transformer is a versatile control power supply solution, ideal for machine tools and mechanical equipment, while catering to the needs of general electrical appliances, localized lighting, and indicating power supply.
· The transformer is designed for altitudes up to 2000 meters;
· Operates efficiently in ambient air temperatures ranging from -25ºC to +40ºC, ensuring that the 24-hour average does not exceed +35ºC.
· The relative humidity conditions are optimal when it does not surpass 90% at +25ºC, and should remain below 50% at +40ºC to ensure optimal performance.
· Suitable for environments free from violent vibrations and shocks, and where exposure to rain or snow is nonexistent:
The transformer thrives in environments free from explosion risks, corrosive gases, and conductive dust that could potentially damage metal components or affect insulation integrity.
Transformers are meticulously crafted with varying structures to meet different capacity, voltage, and usage requirements. They are generally categorized into two main forms: those with a protective shell and those without.
Our transformers feature dual-winding or multi-winding coils, allowing for secondary utilization of multiple taps or windings to achieve the precise voltage and capacity needed for effective distribution.
The double winding transformer coil is calibrated with a primary current of 11=Pe/1 and a secondary current of 12=Pe/U2, ensuring efficiency and reliability.
