This is a 6-channel PCB carrier board for the popular Meanwell LDD-H series of PWM constant current drivers. Use it to build up your custom drivers using the MeanWell LDD-H series of buck drivers. It can be configured to provide specific current capabilities (limits) for each channel such that it is perfectly suited to your setup. A perfect match to get six channel control with your Storm LED Controller. This board is commonly referred to as the "LDD 6up."
The design includes 10K pull-down resistors (pre-soldered to the PCB) to shut off the LED outputs if the PWM signal is disconnected (such as when a controller is reset). This avoids the common problem of having the LEDs go to 100% brightness when the controller is reset. Also includes all necessary terminal blocks & pull-down resistors. Soldering required for assembly.
