Presence Sensor ON/OFF for UV lamps
This presence sensor is a switch that, upon detecting the movement of people, turns off the light of the LED lamp (0% flux). Instead, after a preselected time, when no people are detected, the sensor turns the UV light back on. (100% flow). It is particularly suitable in combination with the use of germicidal UVC lamps. It ensures controlled and effective operation of cabin sanitization systems.
Zero-cross relay operation
Designed in the software, sensor switches on/off the load right at the zero-cross point, to ensure the in-rush current is minimised, enabling the maximum lifetime of the relay
Detection Area
Detection area can be reduced by selecting the combination on the DIP switches to fit precisely for each specific application.
Hold-time
Hold-time means the time period you would like to keep the lamp on 100% after the person has left the detection area.
Sensor operation with the daylight
The sensor will not be triggered if ambient lux level exceeds the daylight threshold preset. For this product, we have set all the threshold setting to “Disable” for better use with UV light where photocell function is not needed.
Precautions and usages
- For safety reasons, the sensor is preset to switch-on after 20 seconds, compared to the time set manually using the switch.
- In case of power cut or power failure, the status after re-powered on will be “OFF” for safety concerns.
- Usage: For maximum UV-light life-span consideration, we recommend to manually switch OFF the UV lights when sterilization is not needed.
N.B. We recommend to select suitable time to carry out sterilization. During the sterilization period, our sensors ensures human safety and switches OFF the UV lights when occupancy detected.
