website | Company information

The Square D brand M-Flex enclosed drive controller provides an adjustable-speed solution for motor-control applications. The enclosed drive controller package features the Telemecanique brand Altivar 61 or Altivar 71 AC drive for process applications where high functionality of features is required.

The M-Flex enclosed drive controllers serve a multitude of market segments, including government, hospitals, universities, pharmaceutical, industrial facilities and municipal pumping applications.

The enclosed drive controllers are available in the following ratings:

-- Constant-torque/heavy-duty ratings, up to 40 hp at 208-230V, and up to 450 hp at 460V using the Altivar 71 AC drive
-- Variable torque/light duty ratings (110 percent current limit) – 1-50 hp at 208-230V, and 1-500 hp at 460V, using the Altivar 61 AC drive

M-Flex enclosed drive controllers are available in Type 1 general purpose or Type 12/12K drip- and dust-proof environmental enclosures in integrated or barriered designs. Integrated enclosures, which can be wall- or floor-mounted, provide a circuit-breaker disconnect and enough room for power peripherals, including isolation and bypass contactors, all within the same enclosure. Enclosures with barriers separate power and control circuits, such as bypass, from drive control to allow for maximum flexibility if servicing a drive-in bypass operation.

Standard integrated features of the M-Flex enclosed drive controllers include an AC line reactor providing transient protection from surge and overvoltage conditions, while minimizing line harmonics to allow the installer to optimize dimensioning of power cables. M-Flex enclosed drive controllers also are configured to meet International Building Code and ASCE 7 seismic-qualification requirements in accordance with the ICC ES AC156 shaker table testing protocol. The enclosed-drive controller is designed and constructed for structural integrity.

All M-Flex enclosed drive controllers have either prepunched conduit knockouts or removable top and bottom conduit plates to save installation time and prevent metal filings from entering the enclosure.

The controllers are expandable. For building automation applications, LonWorks, BACnet, MetaSYS N2 and APOGEE P1 can be added.
