General Description

The MVS Series 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 resistor assemblies,
allowing the soft starter to be tested with a low-voltage motor (< 500 VAC).
This document describes the features of MVS soft starters. This document has
been designed to give engineers a general overview of the functionality of the
MVS.
