GE Vernova LV7000 Low Voltage Drive

Feature & Principle

It is GE Vernova (Converteam/Alstom) LV7000 series modular low voltage frequency converter platform. It adopts modular power unit architecture, supports sensorless vector and closed-loop flux vector control. Different sub-models are used for independent AC drive, common DC bus inverter, active front end rectifier. It can be expanded with fieldbus and I/O option cards, supports master-slave synchronization, winding tension control, and has complete overcurrent, overvoltage and overtemperature protection. This series is widely used for heavy industry production line drive transformation and maintenance.
