Product Features

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