Single-Phase Economic Small Frequency Inverter

The single-phase economic mini inverter is a cost-effective speed control device designed for low-power equipment.  Featuring a compact structure and simple operation interface, it achieves soft start, smooth speed control, and energy-saving operation of motors by adjusting the output frequency. This inverter includes basic protection functions such as overcurrent, overvoltage, and overload protection, ensuring long-term stable operation of the equipment. Its small size, easy installation, and strong adaptability make it particularly suitable for fans, water pumps, small processing machinery, and light-duty household equipment.
Product Application Industries:
Widely used in small cycloidal motors and equipment in low-demand applications.
Product Technical Features:
1. Adopts a 32-bit motor CPU, providing high-frequency output accuracy with a resolution of up to 0.01Hz.
2. Built-in PID control function.
