Product Description
PQ580M Mini Inverter is an economic inverter developed by PQUAN. This inverter is primarily a compact, low-power inverter that utilizes vectorized V/F control technology and compatible with vector control. It offers a variety of commonly used functions such as PID control, multi-speed operation, DC braking, Modbus communication, and multiple macro functions (e.g., constant pressure water supply, machine tool, engraving machine macro functions, etc., easily solving application scenario challenges). With comprehensive functions and a smaller size, it can further reduce installation space. This economical model is designed for small-scale automated equipment and is particularly suitable for low-power transmission applications in electronic equipment, food packaging, woodworking, glass, and other industries.
