Description

The CBU-PWM4 is a Casambi-enabled dimmer designed for constant voltage LED loads, including LED strips and constant voltage LED modules. It functions as an

regulator between a 12-24v DC power supply and the LED load.

With the ability to manage up to four channels, the CBUPWM4 is a perfect fit for RGBW and tunable white (TW) applications. The maximum total output current is 6A, which can be divided among the four channels as needed. The CBU-PWM4 is protected against short circuits, overvoltage, and overcurrent situations, but not

against reverse polarity.

Different fixture profiles can be loaded on the PWM4 for different functionality.

  • Bluetooth mesh controller for tunable white or RGBW LED tape
  • Wirelessly programmable via Casambi app, to create different coloured scenes and automations
  • Requires a separate non-dim power supply
  • Screw terminals
  • Can be provided with installation box if required
  • Compatible with all other Casambi devices, to form a network

Additional Information

  • Casambi uses Bluetooth mesh network technology, allowing each Casambi unit or Casambi Ready product to act as a repeater.
  • Longer ranges can be achieved by using any Casambi unit as a repeater.
  • Range is highly dependent on surroundings and obstacles such as walls and building materials.
