FC808E series Engineering AC Drives Low Voltage-Nietz Electric Co.,Ltd

Features

The FC808E series high-performance engineering inverters are divided into two topological forms: single-machine drive and multi-machine drive. It is a high-performance, high-reliability drive product positioned for high-end drive applications. The voltage level covers the requirements of 400 V and 690 V voltages, and the power range covers 3.7 kW ~ 5600 kW. Whether it is module structure, power density, response and accuracy, they are all leading. The FC808E series inverters can be widely used in continuous production lines such as metallurgy and papermaking, as well as large equipment such as ships, drilling rigs, shield machines, and port quay cranes.
