Lutron®, QSN-4A5-S, Phase Adaptive Fixture Controller, LED, Series: QSN-4A5, 120 to 277 V, 8.3, 16 A, 13.25 in H x 9.25 in W x 3.14 in D Dimensions

• An auto-detect mode is supported to detect and configure forward-phase or reverse-phase dimming for incandescent/halogen, electronic/magnetic lowvoltage and neon/cold cathode light sources
• A locked forward-phase or reverse-phase mode is available
• Controls dimmable LED loads
• RTISS technology compensates for incoming line-voltage variations such as changes in Root Mean Square (RMS) voltage, frequency shifts (up to ± 2% change in frequency /second), harmonics and line noise
• RTISS-ICM technology is able to withstand highinrush LEDs, bulb blowouts and direct shorts
• RTISS-TE technology allows for true instantaneous voltage compensation for incoming line-voltage variations
• Only operates in reverse-phase when voltage-comp is enabled
• Provides air gap off (when all zones are off)
• Integral protection for common temporary over-current and over-voltage conditions
• LEDs on the module provide diagnostic information
• Buttons on the module provide override control
• Emergency contact closure input (CCI)
• Power failure memory automatically returns the outputs to the levels they were set to prior to a power outage
• Bypass jumper provided to easily verify load wiring before connecting loads to outputs
