The module enables the operation of individual LEDs and LED light strips with stable and adjustable brightness. To do this, the module supplies the consumers with a current that can be set in steps and is largely independent of the module's supply voltage and the properties of the LEDs. LED strip lights may have up to 7 LEDs connected in series. Suitable for Viessmann LED light strips, e.g. B. Art. 5086 - 5089. The module has two outputs. The brightness of the LEDs can be adjusted independently for each output using 4 DIP switches (binary) based on the current strength. Starting from approx. 1 mA, currents can be set up to a maximum of approx. 31 mA. The maximum input voltage is 24 V AC.
