NEMA 3R Packaged Drives Keep Things Moving in Outdoor Applications
Engineering and assembling a custom variable frequency drive that fits your application and can handle the stresses of an outdoor location can be a complicated process. Custom-built packages can also increase lead times, engineering costs, and installation complexity. The Reynolds Company's packaged NEMA 3R PowerFlex® drive solutions help eliminate these challenges by providing pre-engineered, configurable VFD packages that arrive ready for installation.
These pre-engineered packaged VFDs combine an Allen-Bradley® PowerFlex™ 750-series drive with a NEMA 3R enclosure to provide a ready-to-install speed control solution for outdoor pumps, fans, compressors, conveyors, and more. Each standard package has the major power and control components already engineered and assembled, including a PowerFlex drive, circuit breaker disconnect, line reactor, and control power transformer. The result is a packaged VFD solution that reduces engineering effort, simplifies field wiring, shortens installation time, and helps keep projects on schedule.
