1pc Frequency Inverter / Variable Frequency Drive (VFD) — models: 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, 5.5 kW Key functions and specifications Function: AC to variable-frequency output converter for motor speed control; adjusts motor speed by changing output frequency. Power options: 0.75KW, 1.5KW, 2.2KW, 4KW, 5.5KW (select one unit per purchase). Input compatibility: 1PH or 3PH supply, 220V / 380V. Output frequency range: 0.1–400 Hz. Format: sold as 1pc inverter / frequency inverter / output converter / variable frequency drive. Why customers need this product Precise motor speed control: allows you to match motor speed to process requirements by setting output frequency from 0.1 to 400 Hz. Broad compatibility: supports single-phase and three-phase inputs at common voltages (220V and 380V), simplifying replacement and retrofit across different installations. Right-sized power choices: multiple kW ratings let you pick the correct model for motors of varying sizes without oversizing equipment. How it solves common problems Process tuning: provides fine control of speed for consistent production or machine behavior where fixed-speed motors cannot deliver required variability. Reduced mechanical stress: frequency control enables controlled acceleration and deceleration to minimize wear on belts, couplings, and driven equipment. Flexible installation: the range of input phase and voltage options reduces the need for electrical reconfiguration when upgrading or replacing drives. Important attributes Function: variable-frequency motor speed control (VFD / frequency inverter / output converter). Compatibility: works with standard 220V and 380V supplies, and accepts single-phase or three-phase input. Performance: wide output frequency range (0.1–400 Hz) for high-resolution speed control across many applications. Models: available in 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, and 5.5 kW power ratings. Quantity: sold as 1pc inverter. Typical use scenarios Pump and fan systems: adjust motor speed to control flow or pressure precisely, improving process control and reducing unnecessary runtime. Conveyors and material handling: match belt speed to production line needs, allowing smooth starts and stops and easier integration with automation. Machine tools and small industrial drives: provide adaptable speed ranges for machining, mixing, or assembly equipment where varying RPM is required. Ordering and selection tips Choose the model with a kW rating at or slightly above your motor’s rated power. Confirm your supply is 220V or 380V and whether you have single-phase or three-phase input before ordering. Sold as a single inverter unit (1pc); select the correct power rating for your application.
