To light up the surroundings of a public or tertiary building when the natural brightness threshold becomes insufficient.
To switch off automatically when daylight is sufficient again.
Up to 15% energy saving by automatically extinguishing lighting when it is not necessary.
Automation ensures major energy savings, increased comfort and enhanced safety.
The IC 100 twilight switch is the ideal product for problem-free management of these needs. Once installed and its threshold set, it will automatically switch on and turn off the lighting at the right time. A built-in time delay avoids untimely closing or tripping during undesired transient brightness conditions.
For higher powers, relay using a CT contactor and its protective circuit-breaker: their ratings depend on installed power and load type
Main Energy Efficiency characteristics
The solution is to set the lighting operation threshold on the IC 100 twilight switch according to the external brightness measured by the wall-mounted cell:
The photoelectric cell detects low brightness, causes closure of IC 50 contact and ensures lighting
The IC 100 monitoring light comes on when brightness threshold is reached and switches off lighting
Time delay on closing and breaking of contact: 10 seconds
Setting the tripping threshold from 2 to 100 lux.
