AC Variable frequency drive(MFC 710 series) for General Purpose 3x400V, 50/60HZ - Product
Place of Origin : Weihai,China
Product Description
Project description:
As main effect of recently carried grants (in cooperation with Institute of Control and Industrial Electronics from Warsaw University of Technology), a new series of sensorless vector frequency converters was worked out (up to 160 kW rated motor power). As a continuation of R&D implementing an extended power range product line (up to 315 kW rated motor power) is planned.
Proposed frequency converters can be used for smooth and precision control of rotational speed of AC m
