Overview
The MVS provides compact and robust soft start solutions for control of medium voltage motors. MVS soft starters
provide a complete range of motor and system protection features and have been designed for reliable performance in the
most demanding installation situations.
Each MVS soft starter comprises two elements:
a power assembly
a controller module
The power assembly and controller module are supplied as a pair and share the same serial number. Care should be
taken during installation to ensure the correct controller and power assembly are used together.
Each MVS is also supplied with two fibre-optic cables, to connect the controller module to the power assembly, and three
non-conduction lead assemblies, allowing the soft starter to be tested with a low-voltage motor (< 500 VAC).
