Customized 0.75KW-5.5KW Three-Phase Inverter with RS485 Interface and CE Certified Variable Frequency Drive

Customized three-phase/single-phase intelligent 0.75KW/1.5KW/2.2KW/5.5KW three-phase inverters, equipped with RS485 interface and single-phase input inverters, CE certified.

The three-phase AC drive system is a complete power system based on three-phase AC power supply, achieving precise control of AC motors through power electronics conversion technology. Its core architecture and performance advantages are as follows:

System Composition: Consisting of a three-phase grid, rectifier unit, DC bus, IGBT inverter, and three-phase induction/synchronous motor. Dynamic voltage and frequency regulation is achieved through PWM modulation, forming a closed-loop vector control circuit.
‌High-Efficiency Characteristics:‌ Achieves a typical power factor of 0.95 under rated load, with system efficiency exceeding 92%. This significantly reduces reactive power losses and thermal waste, delivering 20%-30% energy savings compared to traditional fixed-speed drives.
‌Operational Advantages:‌ Supports soft starts and stepless speed regulation, eliminating inrush currents to extend equipment lifespan. Provides smooth torque output, making it ideal for high-dynamic-response applications such as CNC machine tools and elevator systems.
Industrial Applications: Widely deployed in pumps, fans, compressors, mining machinery, and new energy vehicle electric drive systems, serving as a core execution unit for industrial automation and green manufacturing.
Compliance Standards: Meets IEC 60034 series energy efficiency and safety specifications. Supports three-phase four-wire (380V/220V) power supply with compatibility for both star (Y) and delta (Δ) connections to accommodate diverse load requirements.
