The MiniController Casambi Classic is a control unit for LED modules with Tunable White technology that is only 8 cm long and 1.4 cm wide. The integrated Casambi-ready module enables convenient operation via smartphone or tablet using the Casambi App. Two channels can be used to control either one tunable white module or two monochrome modules with a constant voltage of 12 to 24 V. The controller supports up to 3.5 A per channel. The standby power is approx. 150 mW at a voltage of 24 V. With the help of the app from the Finnish technology company Casambi, which is available free of charge for iOS and Android devices, the brightness and colour temperature of the LED modules connected to the MiniController can be individually controlled. A Dim2Warm mode can also be implemented. The app can also be used to specify whether the last selected brightness and colour temperature values are to be retained after a power interruption.
