Description

CBU-PWM4-LR is a Bluetooth-controllable, 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-LR 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 all output channels. CBU-PWM4-LR is protected against overvoltage, overcurrent and short-circuit situations.
