Power Modular Drives

Control Techniques, an Emerson business, has extended its range of high Power Modular Drives. Both its Unidrive M and Powerdrive F300 variable speed drive ranges are now available in the larger frame size 11, providing a flexible method of building compact, reliable high-power solutions. Paralleled together, Unidrive M can control asynchronous and permanent magnet motors in systems up to 2.8 MW (4,200 HP). The new frame 11 is a 250 kW (400 HP) module that allows system builders to create high power solutions with the smallest number of components, keeping both footprint and costs to a minimum. Unidrive M differentiates itself on performance with extremely fast current control algorithms and high switching frequencies. Active Front End (AFE) solutions deliver unparalleled torque precision and power quality. The Unidrive M modules can be paralleled into a wide range of flexible solutions to solve all system needs including Active Front End and multi-pulse rectifier configurations. They can be controlled by Control Techniques’ Unidrive M600, M700, M701 and M702 controllers. The company also offers a full range of high powered drive products tailor-made for fan, pump and compressor applications from 90 kW to 2.8 MW.
