The i-Series dimmers consist of the iPAK and the iPRO. The i-Series embody the same core design as the e-Series Dimmers, but are intended for permanent installation environments. The list of installation options for the i-Series dimmers include floor mounting, wall mounting and truss hanging. A feature of the i-Series construction is the separate installation frame which allows for easy termination by an authorised electrician prior to construction. This helps protect the dimmer electronics on the main dimmer chassis from plaster, dust, paint and other building debris.
