Medium Voltage Soft Starters AuCom s MVS medium voltage soft starters are an integrated solution for motor control and protection. MVS soft starters combine advanced soft start and soft stop functionality with extensive motor and system protection, plus a user-friendly interface and complete commissioning diagnostics. MVS Series starters provide integrated motor starting and monitoring functions for the most demanding industrial situations . Advanced algorithms ensure ultra-smooth starting and stopping, and fully adjustable protection features maximise electrical and mechanical protection for your motor and system. A large-format display and detailed performance logs make setup and operation simple. MVS soft starters are available in IP54 enclosures, with options for line and bypass contactors, earthing and isolation switches. AuCom can also design and build enclosures to meet particular specifications , and we offer full applications engineering support at all stages of the design process. For customers who prefer to build their own enclosures, MVS soft starters can be supplied in IP00 format or as a kit for local assembly. MVS soft starter have been installed in high-profile locations worldwide. By integrating motor protection with soft start and soft stop control, the MVS provides a simple and cost-effective solution for most major applications . The MVS soft starter includes numerous user-friendly features to ensure safe and easy operation, and has the flexibility to meet the demands of all medium voltage situations.
