5.5kw 7.5kw 11kw 15kw 22kw 380v Frequency Inverters Converters AC Drive/VFD/Speed Controller

Description

The 5.5kW, 7.5kW, 11kW, 15kW, and 22kW 380V Frequency Inverter Converter AC Drive (VFD – Variable Frequency Drive / Speed Controller) is a high-performance industrial power control device designed to regulate and optimize the speed, torque, and performance of three-phase AC electric motors. This advanced drive is widely used in manufacturing, automation, industrial machinery, HVAC systems, water pumps, compressors, conveyor belts, CNC machines, and many other applications where precise motor control and energy efficiency are essential.

This frequency inverter operates on a 380V three-phase power supply, making it suitable for heavy-duty industrial environments and commercial applications. It converts fixed-frequency AC power into variable-frequency output, allowing users to adjust motor speed smoothly and accurately. By controlling the frequency and voltage supplied to the motor, the VFD helps reduce energy consumption, minimize mechanical stress, and extend the lifespan of connected equipment.

Available in multiple power ratings — 5.5kW, 7.5kW, 11kW, 15kW, and 22kW — this inverter is versatile and adaptable to different motor sizes and load requirements. The range of options makes it ideal for small, medium, and large-scale industrial operations. Each model is built with robust internal components, high-quality electronic circuits, and an efficient cooling system to ensure stable performance even under continuous operation.

The inverter features an intuitive digital control panel with a clear LED or LCD display that allows operators to monitor real-time parameters such as output frequency, voltage, current, motor speed, and operational status. Users can easily adjust settings through the keypad or connect the device to an external control system via standard communication interfaces such as RS485, Modbus, or PLC compatibility, depending on the model.

Safety and protection are key aspects of this VFD. It includes built-in protective functions such as over-voltage protection, under-voltage protection, over-current protection, overheat protection, short-circuit protection, and overload protection. These safeguards help prevent damage to both the inverter and the connected motor, ensuring reliable and safe operation in demanding environments.

The inverter also supports soft start and soft stop functions, which gradually ramp up or slow down motor speed instead of sudden starts and stops. This reduces mechanical wear, prevents power surges, and improves overall system efficiency. Additionally, it helps lower maintenance costs and minimizes downtime in industrial operations.

Designed with durability in mind, the unit is housed in a strong metal or high-grade plastic enclosure that protects internal components from dust, vibration, and environmental interference. It is suitable for installation in control cabinets, machine rooms, or industrial panels.

Overall, the 5.5kW–22kW 380V Frequency Inverter Converter AC Drive/VFD/Speed Controller is a reliable, energy-efficient, and high-precision motor control solution that enhances productivity, reduces energy costs, and improves the performance and longevity of industrial machinery.
