General-Purpose Variable Frequency Drive Inverter 3AC 380V~460V 0.75KW~630KW
Universal high performance drive vector control function inverter.
The inverter-controlled speed control system is based on advanced
technical control theory and intelligent control means to achieve
extremely high responsiveness and stability.
Small size, high precision, easy operation, high reliability,
multi-layer protection of equipment, better than any previous speed
regulation mode. The utility model has the advantages of simple
structure, wide speed regulation range, high speed regulation
precision, convenient installation and debugging, perfect
protection function, stable and reliable operation, and remarkable
energy saving effect.
