Dusk/Dawn Effect Lighting Controller Module, 230Vac 50Hz, 750W

This 230Vac 750 Watt Dusk/Dawn Effect Lighting Controller Module will progressively adjust lighting brightness over a user set time period to mimic either sunrise (Day Effect) or sunset (Night Effect).

• User adjustable Dawn (Dusk) transistion time from 1 Second and 120 Minutes
• Day Effect cycle provides a progressive increase in the output from completely Off to completely On
• Night Effect cycle provides a progressive decrease in the output from completely On to completely Off
• Unit will automatically start if either mode is selected on power-up
• Transition can be paused at any time by having neither mode selected
• Rated to switch resistive loads from 50 to 750 Watts

The Day/Night Effect inputs is normally connected to a 2-position SPDT toggle switch (not included) so the user can switch between the Day or Night cycles. Activating the Day Effect input will initiate the sunrise/day cycle. Output will remain in the "day" state (fully on) indefinitely. Releasing the Day Effect input and activating the Night Effect input will initiate the sunset/night cycle. It will then remain in the "night" state (fully off) indefinitely or until the Day Effect is initiated. If a 3 position SPDT switch is used the transition can be stopped at any point by selecting the centre position (neither cycle selected).

The Day/Night Effect inputs can also be connected to the SPDT relay output of a cyclical timer (e.g. VM188) for automatic and continuous switching between Day and Night cycles with quiescent adjustable times provided by the timer to produce a repeating virtual day effect of a duration to suit you needs.

The following adjustments/controls are available to the user:

• Dawn/Dusk transition period (Ramp): 1 Second to 120 Minutes (one trim-pot sets both dawn and dusk to the same transition time)
• Day/Night Effect inputs to select which cycle is activated
• Day/Night Effect inputs can be connected to a timer to produce a virtual-day effect
• Reset input to restart the cycle from initial state as determined by the Day/Night Effect inputs

Useful in a variety of applications including poultry-farming, design studios, security and safety lighting and children's bedrooms.

The module is supplied fully assembled and has an onboard safety fuse and LED 'On' indicator. All you need to do is house it in a suitable enclosure, add the wiring, switches and lights.
