1pcs Frequency Inverter (Variable Frequency Output Frequency Converter) — available in 0.75KW, 1.5KW, 2.2KW, 4KW, 5.5KW Why you need this product Precise motor speed control: adjust motor RPM smoothly to match process requirements, improving product quality and reducing waste. Energy and wear reduction: variable speed operation lowers energy use for throttled loads and reduces mechanical stress from frequent starts/stops. Flexible installation: supports common supply and motor configurations so one unit can serve many applications. Key benefits and how it solves problems Wide output frequency range (Output Frequency: 0.1-400HZ) lets you run motors at very low or high speeds without external gearboxes or mechanical modifications. Compatible with single-phase and three-phase supplies (1PH/3PH) and supports 220V and 380V systems, minimizing inventory and simplifying replacements. Available in multiple power ratings (0.75KW, 1.5KW, 2.2KW, 4KW, 5.5KW) to match motor sizes and load requirements precisely. Important attributes Function: Frequency inverter / variable frequency drive for AC motor speed and torque control. Compatibility: 1PH/3PH configurations; 220V and 380V compatible. Performance: Output Frequency range 0.1-400HZ for fine-grained speed control. Quantity: 1pcs per order. Construction: Designed for industrial and commercial applications with reliable performance under typical operating conditions. Practical applications (examples) Pump control: Maintain constant pressure or flow in water treatment and irrigation systems by adjusting pump speed to demand. HVAC and fans: Reduce energy consumption and noise by matching fan speed to ventilation and temperature control needs. Conveyor and material handling: Smooth start/stop and variable speed for conveyors, feeders, and assembly equipment to improve throughput and reduce product damage.
