"Rampa" - automatic dimmer: dawn and dusk simulator for LED

The low-cost “RAMPA” module is designed to perform soft start and stop for LED stripes and other 12V/24V light sources. Additional outputs may provide PWM signal for other LED drivers as well.

“RAMPA” successfully prevent unpleasant glare effect related to sudden illumination. It also significantly increases the visual effect of LED light.

Brightening/Dimming period is selectable: 0.5, 1, 2, 5 seconds and 1, 30, 60, 90 minutest. That is you can also obtain dawn and dusk simulation effect with e.g. 30minutes period.

It's great for exotic birds, terrariums, aquariums and other things like stairs backlight, etc.

Installation and usage is easy and intuitive – just throw the module in-between power supply unit and LED stripe.
