4-Channel PWM Casambi Controller (Long Range)

Four independent PWM output channels at 12–24V DC for controlling RGB, RGBW, tunable white, or multi-zone LED strip installations. The long-range Bluetooth radio ensures reliable Casambi mesh connectivity across large open areas, retail floors, and hospitality environments.

Key Benefits

Why choose the CBU-PWM4-LR

RGB, RGBW & tunable white

Four independent channels cover every strip configuration — single colour, tunable white (warm + cool), RGB, and RGBW — all from one module with precise individual channel control.

Extended Bluetooth range

The long-range radio maintains a stable Casambi mesh connection even in large open-plan spaces, eliminating the need for extra repeater nodes in medium-scale installations.

Smooth, flicker-free dimming

High-frequency PWM output eliminates visible flicker, delivering cinema-quality smooth dimming curves suited to hospitality, retail display, and broadcast-adjacent environments.
