The product relies on the market application demands as the background to meet the market development demand for high-performance modular VFDs. With the unit modular design, you can conduct parallel operation as needed. Quick installation can meet customized needs with high market compatibility. The product conforms to the industrial theme of intelligence, automation, high efficiency and energy saving.Practicality embodiment: （1) Using the quick DC bus bar connection method, the product realizes quick parallel operation, and greatly saves wiring time and cost. Compared with the traditional VFDs, the product also solves the problem of layered installation, and maximizes the cabinet space utilization, saving 30% of the cabinet installation space. （2) With structure design optimization and cost reduction, the rectifier and inverter modules share the same mold, and you conduct parallel operation as needed. （3) The streamlined and intelligent control panel with convenient operations meets the HMI operation requirements. Each module is distinguished by the color matching of functional parts to achieve efficient identification of the modules while meeting structural functions.Aesthetic embodiment: Based on the concept of 'Form follows function',the product breaks through the inherent impression of traditional industrial control equipment, takes the brand PI planning into consideration, uses the brand character letter //
