The Lutron PowPak RMJ-ECO-32-DV-B wireless dimming module is designed to operate up to 32 Lutron EcoSystem dimmable ballasts or LED drivers, based on input from Lutron's Pico remotes and Radio Powr Savr sensors. Operating on 120 or 277 volts, it can receive wireless inputs from up to nine Pico remotes or six Radio Powr Savr occupancy/vacancy sensors. Install this module in the center of the room for maximum transmitter coverage. The PowPak dimming module is a perfect energy-conserving solution for small areas such as classrooms, private offices, and conference rooms. Combined with EcoSystem dimming ballasts, this wireless sensor can automatically adjust lights in response to available daylight, resulting in minimized glare and heat gain.
