New LED Control boards released
If you want to control the power output of your LED lighting, you can use the LPF-xxD LED powersupply controller range for this. These power supplies come with an control signal input. By controlling the resistance on the control cable, you can control the actual light output (constant current limiting).
To easily control this "control signal", I have designed a simple PCB. It just require an opto isolator and some resistors.
You can purchase the boards as a kit, where you (simply) have to solder on the components or you can buy them ready to use.
