CVD291 Series DALI Decoder
Model：CVD291 / CVD291-TC / CVD291-RGBW
4-channel constant-voltage LED driver (DALI decoder) with 0.1%–100% dimming and 3125Hz flicker-free dimming frequency, supporting DT6 / DT8-Tc / RGBW light sources.
- 4-channel constant-voltage LED driver for 12V or 24VDC CV LED strips and modules
- DALI control gear compliant with IEC 62386-101/-102/-207/-209; for DALI-2 application controllers, also compatible with DALI-1 systems
- Control variants: 1–4 short addresses DT6, 1 or 2 short addresses DT8-Tc, 1 DT8-RGB or DT8-RGBW
- 0.1%–100% dimming; 3125Hz dimming frequency (flicker-free per GB/T 31831-2015)
- Output PWM frequency selectable: 1000Hz / 3200Hz
- 12–24VDC powered, over-voltage and over-current protection, total current up to 8A
- Compact design for tight spaces
