Variable Frequency Drive (Converter / Inverter) — AC Motor Speed Controller Key specifications Available as 1 pcs units in these power ratings: 0.75 kW, 1.5 kW, 2.2 kW, 4 kW, 5.5 kW Input/compatible voltages: 220V and 380V Output frequency range: 0.1–400 Hz Function: variable frequency drive / inverter to control AC motor speed and torque Why you need it Precise speed control: adjust motor speed across a wide frequency range (0.1–400 Hz) to match process requirements rather than running at fixed RPM. Energy and cost savings: match motor output to load demand to reduce power consumption and operating costs. Smoother operation and reduced wear: controlled startup and speed changes lower mechanical stress on motors, belts, pumps, and gearboxes. Flexible integration: one product covers multiple power classes and two common supply voltages, making it easier to standardize on-site equipment. What makes this product stand out Broad power range (0.75–5.5 kW) supports a variety of small- to medium-sized motor applications without overspecifying equipment. Wide output frequency range enables very low-speed operation and high-speed capability for versatile process control. Designed for AC motor speed control and conversion between line voltage and controlled output frequency. Performance and compatibility Compatible with standard 220V and 380V AC installations and a range of AC motors (refer to motor nameplate for exact matching). Delivers precise frequency output up to 400 Hz for stable speed regulation and repeatable performance. Suitable for continuous industrial and commercial use where reliable speed control is required. Typical applications Pump and fan control: optimize flow and pressure in HVAC, water treatment, and irrigation by varying motor speed instead of throttling. Conveyor and material handling: maintain consistent throughput and gentle starts to protect conveyed goods and reduce maintenance. Machine tools and mixers: control spindle or agitator speeds for improved process quality and reduced product waste. Ordering and selection tip Choose the unit rated closest above your motor’s rated power and match the system voltage (220V or 380V) to your supply to ensure reliable operation. For any specific installation requirements, consult an electrician or control engineer to confirm compatibility with motor type and system wiring.
