The E7C Configured package provides an E7 drive in a NEMA 1 or NEMA 12 enclosure, with space for several commonly used options, such as reactors, RFI filters, circuit breakers, etc.

The E7 Drive is a variable torque AC drive, designed specifically for HVAC applications in building automation. A new benchmark for size, cost, performance, benefits, and quality, the E7 includes numerous built-in features such as network communications, H/O/A, PI control, and energy-savings functions.

The E7C has embedded communications for the popular building automation protocols, Johnson Controls Metasys® N2 and Siemens APOGEE™FLN, as well as Modbus. Optional LonWorks®, EtherNet/IP and Modbus TCP/IP interface cards are available.
