Casambi 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.
CBU-PWM4-LR can be controlled with the Casambi App, available for iOS and Android devices, as well as with traditional wall switches. The Casambi App can be downloaded free of charge from the Apple App Store and Google Play Store.
Different Casambi-enabled products can be used from a simple one-luminaire direct control setup to a complete and full-featured lighting control system, in which up to 250 units automatically form an intelligent mesh network.
The CBU-PWM4-4-LR can be controlled with the Casambi app, available for iOS and Android devices. The Casambi app can be downloaded free of charge from Apple App Store and Google Play Store.
