Packaged AC Drives
E-flex™

E-flex AC drives are packaged, adjustable speed drive solutions for commercial and industrial pump and fan applications. The E-flex drive is the perfect solution for large HVAC systems where flexibility, functionality, structural integrity, ease of use, and reliability are concerns for the user.

Square D product details, like standard options and HVAC control interfacing, allow users to stay focused on their business and not ours. E-flex AC drives utilize Altivar® 61 drive technology in a unique packaged power converter ("flex-drive") design that extends the specification ratings beyond a standard Altivar 61 drive. E-flex drives are compatible with Altivar 61 communication cards, I/O extension cards and operator interface options.
