Schneider ATV31CU40N4 VFD

Feature & Principle

It is a cabinet-type enclosed frequency converter of Schneider Altivar 31 series. It converts fixed-frequency AC power into adjustable voltage and frequency output to realize stepless speed regulation of three-phase asynchronous motors. Built-in EMC filter suppresses electromagnetic interference. IP55 enclosure can be installed directly on site without extra control cabinet. It supports basic V/F control and multiple protection functions, suitable for equipment in dusty or humid workshop environments.
