OS-475A-M is an automatic light switch integrated with PIR motion sensor and light sensor which can be used to switch on the light when movement is detected and the ambient light level is below the pre-set Lux control value; lights will automatically be switched off after the pre-set time reached and no movement is detected, to save energy cost.
Rated voltage: 220-240Vac 50/60Hz
Load: Max. 10A for lighting
Detection angle: 180 degrees
Detection range: 8 meters
Adjustable Lux, Time, Meter and Mic. (for acoustic sensor)
With acoustic sensor for enhancing detection performance
With Lux learning function for teaching in ambient light value to provide flexibility in Lux control setting
Three operating modes settable: Auto, Manual on, Manual off
