SylSmart SSC PWM4 is a Bluetooth controllable, four channel PWM dimmer for constant voltage LED loads, such as LED strips and constant voltage LED modules. 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. Note: Device must be configured using the SylSmart Standalone App sto select the mode of operation.
