Unidrive SPMs
Unidrive — 60 hp to 2900 hp
FEATURES BENEFITS
• Control high current motors by paralleling output
inverter modules
Build customized high power drives with standard
volume produced modules
• Compact IP20 input and output power modules
Create a comprehensive range of custom power systems
• Utilize an existing DC supply
Economic integration with existing plant
• Return braking energy to AC supply with standard
inverter modules
Reduce running cost
• Recycle energy between simultaneously motoring
and regenerating drives
Ideal for unwinding / winding processes
• Enable a single AC power entry
Simplify installation and minimize cabling
• Minimize harmonics with 12-, 18- and 24-pulse
rectifier configurations
Meet more demanding supply regulations
• Eliminate harmonics with an active front end
Comply with supply regulations
• IP54 heatsink with through panel mounting
Allows smaller enclosure size, reduces cooling
requirements
Modular drives ideal
for system integrators
and OEMs
The Unidrive SPM — Solution
Platform Modular systems give
integrators and OEMs added
flexibility to design and build
high power AC drives that meet
their exact requirements.
The Unidrive SPM platform
offers all of the standard and
optional features available
on the panel mount SP
drives and is integrated
using the same software
tools for commissioning and
programming.
The modular nature of the power circuit allows drive systems to be constructed in non-standard enclosures. For
example, it is possible to implement a drive system of between 60 and 2900 hp in an enclosure no taller than 36 in.
