ZFeng 900 Series 45Kw-T-G General Vector Variable Frequency Drive

Variable frequency drive (VFD), also known as variable frequency drive or drive controller, is a power control device that integrates frequency conversion technology and microelectronics technology. It achieves precise control of AC motors by changing the frequency of the motor's operating power supply.

• Energy saving: By precisely controlling the speed and power of the motor, significant energy-saving effects can be achieved.
• Wide speed range: It can achieve stepless speed regulation to meet the needs of different working conditions.
• Complete protection function: equipped with multiple protection functions such as overcurrent, overvoltage, overload, etc., to ensure the safe and stable operation of the equipment.

• Precise speed regulation: The frequency converter can adjust the motor speed according to actual needs, avoiding the motor from running in an inefficient state for a long time, thereby significantly reducing energy consumption. According to relevant research, frequency converters can achieve a 20% to 50% reduction in energy consumption in many application scenarios.
• Reducing carbon emissions: By reducing energy consumption, frequency converters can help reduce the consumption of fossil fuels, thereby lowering carbon emissions and meeting the goals of sustainable development.
• Reduce noise pollution: The frequency converter can ensure that the motor remains stable during the starting, accelerating, decelerating, and stopping processes, reduce mechanical vibration and noise, and improve the quality of the working environment. In situations where ventilation, air exchange, cooling, and dust removal are required, such as in the textile and chemical industries, frequency converters can meet production needs and effectively reduce noise pollution by precisely controlling the speed of fans and pumps.

Variable frequency drives are widely used in various fields due to their excellent speed regulation performance and energy-saving effect, including but not limited to:

• Air conditioning load class: used to drag the refrigeration pump, cold water pump, and fan of the air conditioning system to achieve energy saving.
• Industrial equipment: ball mills, rolling mills, winches, roller conveyors, etc., using variable frequency speed regulation can improve equipment reliability and stability.
• Pump loads: including water pumps, oil pumps, chemical pumps, etc., using variable frequency speed regulation can save electricity and reduce mechanical wear.
• Elevators and elevated tour buses: Improve the dynamic characteristics and reliability of elevators, increase the sense of safety, comfort, and efficiency of passengers.
• Environmental protection loads: such as industrial wastewater treatment, garbage power plants, control of industrial smoke exhaust and dust removal, etc.
• Other fields: production lines such as glass, ceramics, pharmaceuticals, beverages, food, packaging, as well as offshore oil platforms, submersible electric pumps, etc.
