Description

Product introduction

ME700 series engineering drives are common DC multi-drive inverters specially designed and developed for heavy-duty mechanical equipment in the rubber industry. The product adopts advanced vector control technology and torque control technology, which not only has the same excellent control performance as the international reliable inverter, but also combines the application characteristics of the rubber machinery industry to further strengthen the reliability of the product and the adaptability of the environment and customer satisfaction. The optimized design can better meet the needs of various transmission applications.

 

advantage

STEC ME700 series engineering inverters can provide two rectification methods, users can choose silicon controlled rectification method or AEF active rectification method according to specific needs. This series adopts a compact modular design, and users can choose individual power modules to combine or complete cabinet products according to their own needs. This series has abundant port resources, provides users with powerful programmable functions, and can meet various application requirements of different industrial sites. This series has several functions:
