DIN rail twilight switch MEMO AST LUX

Astronomical switch witgh twilight probe particularly indicated for the management of shops lighting and luminous signs in general. The initial configuration requires the activation of the load from sunset to sunrise and during the daytime hours in case of low light. This operation can be modified and customized by the user. Alternatively, memo AST LUX can be used as a programmable twilight in which the activation of the load occurs when the probe detects a low light condition and only if the programming (daily or weekly) requires it. The wide display allows to view the date, the time and the relay status. The “keypad lock” function by password, useful for example for installations in public places, prevents unauthorized people from doing setting modifications. The cover on the instrument allows the replacement of the backup battery once discharged. Power supply - 230V AC - 50/60Hz Installation - on DIN rail Programming - daily/weekly + astronomical Programming resolution - 1 minute Luminosity range - OFF, 3÷500 lux, ON Number of relays - 1 automatic time change (DST) - yes (can be programmed) Dimensions - 2 DIN modules Astronomical switch with twilight probe particularly indicated for the management of lighting systems, luminous signs, fountains, etc., with two types of operation: • astronomical operation during the night time band and with daytime switching on thanks to the twilight probe if the brightness falls below the threshold • programmable twilight operation with switching on when the brightness falls below the threshold and only if the programming (daily or weekly) requires it
