Cooper Controls OSW-P-0451-MV-W Greengate 120-277-Volt Single-Level PIR Wall Switch Sensor, White Finish [並行輸入品]

商品説明

NEMA WD7 Guide robotic method utilized to verify coverage patterns. The Greengate OSW-P-0451-MV-W 120-277 Single Level Wall Switch Sensor is a self contained, energy saving, motion-sensing lighting control which replaces a conventional wall switch and utilizes ultrasonic technology to detect room motion. The sensor produces a low-intensity, inaudible sound to detect occupancy in a room. Changes in the sensor's acoustic wave caused by motion, such as walking into a room, reaching for a telephone or swiveling in a chair, will cause the lights to turn on. The sensor does not respond to audible sound. The OSW-P-0451-MV-W time-delay is adjustable from 15 seconds to 30 minutes. Greengate wall switches are ideal for smaller spaces where you will not have obstructions of line-of-sight due to switch location, room orientation or furniture placement. An air-gap switch ensures no leakage current to load for maximum product reliability, and zero-crossing technology maximizes relay life and ensures wall switch longevity. The NEMA WD7 Guide robotic method is utilized to verify coverage patterns, there is no minimum load requirement, and the OSW-P-0451-MV-W has 120 and 277 volts in the same unit. For indoor use only, the switch operates in temperatures of 60 to 80-degrees Fahrenheit (15 to 26-degrees Celsius), and relative humidity of less than 95-percent, non-condensing. The switch plate has a white finish, is only 4.15 inches high by 1.94 inches wide (10.54 cm by 4.92 cm), and the sensor's cover range is 180 degrees, up to 450 square feet (137.16 square meters). It's versatile for any office, board room, conference room, or small enough for a utility room. The switch is compatible with magnetic and electronic ballasts, and the lack of extra parts and pieces makes these systems simple to specify and cost-effective to own.
