Compact DC Power Supply PW2

Compact DC Power Supply


The DW, PW, and UW WattStopper Wall Switch Sensors are ideal for PW Series Passive Infrared technology, PIR, senses occupancy by detecting the difference between heat emitted from the human body in motion and the background space. UW Series passive ultrasonic detection works by transmitting ultrasonic sound waves throughout an area and measuring the speed at which they return. Occupant movement changes the frequency at which these sound waves return, resulting in a Doppler shift and occupancy detection. DW Series Dual Technology (Infrared and Ultrasonic) combines the best of both PIR and ultrasonic technologies. While PIR and ultrasonic sensors provide optimal control for many spaces, some applications pose difficulty for single technology products. Dual technology sensors ensure maximum sensitivity and coverage in tough applications for optimal reliability and energy savings.
