Product Description

LNC500 series General-Purpose Inverter Single-Tube frequency converters are developed based on a brand - new software and hardware platform. In order to better meet the market demands of mechanical equipment such as machine tools, printing, textiles, chemical fibers, stone materials, and engraving, this series of frequency converters features high power density, complete protection functions, and comprehensive application functions. It supports the standard Modbus communication protocol (Note: For frequency converters with a power of 7.5kW 380V and below, and 5.5kW 220V and below, the communication interface is on an independent communication card. When placing an order, if you note "communication card", the standard 485 communication function will be included. Frequency converters with a power above 7.5kW 380V and above 5.5kW 220V come with the standard 485 communication function). Power range:0.75kW-5.5kW-220V,0.75kW-37kW-380V.
