Dimmer for constant current LEDs

Low voltage dimmer for dimming LEDs operated with constant current. The dimmer has three connections on the board with clamping device:

- Input = operating voltage 9V...36V DC
- Output max. 32V (for version 350mA), 28V (for versions 500mA and 700mA) DC
- Connection for push button (not included)

Functionality
1. push button short = channel on
2. push button = light becomes brighter
3. release push button = current brightness is saved
4. press button = light gets darker
5. release button = current brightness is saved
6. processes 2-5 are repeated
7. briefly confirm button = channel off

With memory function, i.e. the last setting remains stored when the power supply is switched off.

Protection functions

- LED Open-Circuit Protection: If there is an interruption in the load circuit, the device switches off.
- LED Short-Circuit Protection: In case of short-circuit in the load circuit, the current is limited to its set value
- Thermal Protection: If the permissible temperature of the circuit is exceeded, the device switches off.

Note: The maximum cable length at the push button should not exceed 1000mm.
