MV4 Series
The compact, general purpose medium voltage drive
ecomagination
Drive technology for the challenges
of tomorrow
Enabling increased efficiency,
accuracy and flexibility in your
processes, GE offers an advanced aircooled medium voltage drive for
efficient motor control. Building on
our extensive experience, the MV4
Series drive provides a flexible modular
approach using common building
blocks to achieve a customized
solution. Easy to install and maintain,
the MV4 Series can save space in
the electrical room, and offer high
availability – all critical factors to
improving your performance and
process effectiveness.
All MV4 Series drives come equipped
with Visor Connect – a remote
monitoring system which connects
the device to GE’s global experts
for immediate service support
when needed and helps prevent
unscheduled downtime.
The MV4 Series is part of GE’s medium
voltage drive family which offers a
wide power range at various voltages
to cover a variety of applications.
Benefits:
• Simpler, smaller and lighter
with high performance
Our high efficiency drive provides
low heat losses and low harmonics
in a small footprint, without the need
for a transformer and external filters.
• Modular ratings and a common
building block with à la carte option
packaging
Scalable in power rating with fewer
spares required and low cost of
ownership.
• Multilevel medium voltage topology
using standard low voltage IGBTs
and modular building blocks that are
quick and easy to service.

Why a variable frequency drive?
Appropriate power usage
of your process
Variable frequency drives (VFDs)
regulate motor speed to control the
flow and pressure of blowers or pumps
without dampers or throttling valves.
This results in energy savings and no
output waste. VFDs also provide a soft
start to the motors, reducing the stress
on driven load and resulting in lower
maintenance costs.
in response to load
A VFD manages power based on actual
demand and uses only the energy
required by the driven equipment to
provide valuable energy savings.
Avoid peak demand charges
When starting large motors with VFDs,
current inrush peaks are eliminated.
The VFD gradually ramps the motor
up to speed by varying output voltage,
current and frequency for a soft start.
