Unidrive SP Modular

Unidrive SP Modular - Power system flexibility

60 hp – 2,900 hp (45 kW – 1.9 MW)

230 V | 460 V | 575 V | 690 V

Unidrive SP Modular delivers all the benefits of the Unidrive SP control platform combined 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 in 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, are 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.

SPM Power Selector Automatic selection/de-selection of drive modules






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 330 kW drive system containing three power modules in parallel could be reconfigured to control three 110 kW 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 the 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 45 to 1900 kW (60 hp - 2,800 hp) in an enclosure no taller than 1m (40") high.
