The CBU-PWM4 is a Casambi four channel PWM dimmer for constant voltage LED loads, such as the Visiolite LED strips. It can be powered by a Visiolite 24 VDC LED driver.

The 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 4 A (North America) / 6 A (international) which can be freely divided between 1-4 channels. CBU-PWM4 is protected against overvoltage, overcurrent and short circuit situations.

All Casambi products can be controlled with the Casambi app which 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 to a complete and full-featured light control system where up to 127 units (Classic) or 250 units (Evolution) form automatically an intelligent mesh network. Dali, Phillips Hue Compatible, and many other systems.
