Unidrive SP Modular
Unidrive SP Modular - Power system flexibility

45kW - 1.9MW (60hp - 2,800hp)
200V / 400V / 575V / 690V

Unidrive SP Modular offers all of the benefits of the Unidrive SP control platform together with maximum power system design flexibility. Drive modules may be connected together in a variety of ways to create custom power conversion schemes such as, common DC bus systems, active input systems for returning excess energy to the power supply and parallel drives for high power motors.  The units can also be used for bulk power inverters for renewable energy systems.


Unidrive SP control with Modular power system flexibility
Unidrive SP Modular has the same control platform as the Panel Mount drives range, offering three option module slots, integrated automation control and high performance motor control.

Maximum Reliability
Unidrive SP Modular units offer maximum reliability, they mass-produced in high volumes and are proven in a wide range of applications, from high power fans to large cranes, and renewable wave energy systems to metal production.

Flexibility is Modular
The Unidrive SPM range comprises key modules that can be combined elegantly to achieve your design criteria with maximum economy.

The NEW SPM Power Selector
The SPM Power Selector is a new addition to the SPM range, it allows the sizing of drive systems to be dynamically modified to suit the application.

  • Redundant / fault tolerant systems can be designed, allowing unserviceable units to be isolated, allowing the rest of the system to continue operating,
  • Allows a system containing multiple power modules to be dynamically reconfigured, for example, a 330kW drive system containing three power modules in parallel could be reconfigured to control three 110kW motors.
  • The size of the inverter can be dynamically resized, for example, automotive dynamometers are often used to test a wide range of vehicles, resizing the inverter to match the required torque improves current measurement resolution and improves test performance.

Low Harmonic Solutions
Control harmonics through Active Front End (AFE) solutions or 12, 18 and 24 pulse operation, ensuring you meet and exceed  supply regulations.

Easy maintenance
Large power conversion systems are usually bulky and require maintenance personnel to be competent to diagnose problems at component level. Unidrive SP Modular removes this requirement, service engineers can exchange compact drive modules on site for units that have been factory built and tested.

Non-Standard enclosures
Ultra compact modules allow high power systems to be constructed in existing or non-standard enclosures, for example, it is possible to implement a drive system of between 45kW to 1900kW (60hp - 2,800hp) in an enclosure no taller than 1m (40") high.
