Automatic PWM soft start LED Dimmer
Description
Automatic PWM soft start LED Dimmer. Soft Start Stop sunrise and sunset automatic dimmer
The device is designed to carry Soft-Start / Stop LEDs and simulate dawn of time: 1, 2, 5, 30 seconds and 1, 5, 30, 60 minutes.
Automatic dimmer up- and down fading
LEDs with series resistor: "An automatic LED Lamp Module" to work directly with LED strips and other LED lamps in the configuration. The system can also be set-point signal, drivers and power supplies for high power LEDs, as long as these systems allows dimming input (usually as a PWM / release / DIM). The increase in brightness in the range of 0-100%, 0.025%, or a resolution of 4000 steps (~ 12bit). The device uses algorithms correction and interpolation to the characteristics of the PWM LED corresponding brightening of the perception of the human eye. The device makes it possible to initiate the process of brightening / dimming via an external start-stop button or other trigger -Signalspannung 3 .. 36V. Maybe you want to achieve full automation, instead of the release button must put daily the relay with timer.
"An automatic LED dimmer module" a transistor output type "open drain" to allow direct control of the receiver with a maximum load current of 5A (60 / 120W at a voltage of 12 / 24V DC).
Time Fade In / Out Board is configured with jumpers. The device can be directly after the
To operate switching voltage and then is only brighten possible.
If the device is operated even in standby mode, a soft start and stop, it is possible.
With this module, the sunrise and sunset can simulate.
