ABB DWA-2 Twilight Astronomical Switch 2 Channel 2CSM222501R1000
Product Description
-
The astronomical switches DWA2 with 2 channel, automatically control lighting circuits depending on the time of sunrise and sunset, greatly increasing energy efficiency
-
The programming is in fact based on a mathematical algorithm able to calculate the time of the rising and setting of the sun in a certain location for each day of the year
-
Once powered the device, simply insert date, time, geographical coordinates and time zone so that it is ready to work
-
These settings can also be automatically defined using the DBT Timer APP
-
The installation of astronomical digital time switches is particularly useful when using a twilight switch with external sensor is not recommended because it may be subject to malfunctions caused by air pollution, excessive brightness or vandalism
-
DWA2 are also indicated for the control of public lighting, shop windows of shops, neon signs, monuments, facades, illuminated fountains
