4-channel BLE PWM dimmer

A four channel PWM dimmer CBU-PWM4 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. The dimmer has four controllable channels making it an ideal product for RGBW and tunable white (TW) applications.
