Dimmers-PWM >PWM4



CBU-PWM4 is a Bluetooth controllable, Casambi enabled four channel PWM dimmer for constant voltage LED loads, such as LED strips and constant voltage LED modules. It is connected between a 12-24 VDC power supply and the constant voltage LED load

CBU-PWM4 can control up to four channels making it an ideal partner for RGBW and tunable white (TW) applications. The maximum combined output current is 6 A which can be freely divided between 1 -4 channels. CBU-PWM4 is protected against overvoltage, overcurrent and short circuit situations.


This device is a 4 channel LED Dimmer with Casambi module integrated inside. It allows to control White, Tunable White, RGB or RGBW led lights (thinks to dedicated Casambi profiles), regulating the intensity of brightness, creating scene and setting different colour effects with just one tap to APP Casambi. The control can be done by smartphone through the user-friendly Casambi application (available for iOS and Android), and by a local command (normally open push button). Supply voltage is from 12 to 24 Vdc. The output voltage varies on supply voltage range and allows to drive LEDs in voltage (CV) up to 5A per channel (max 10A tot.).
