One Driver, Every Way You Want to Dim
Most projects don't settle on a control system until well into the install — the BMS spec changes, a client asks for a simple wall dimmer instead, or a zone gets DALI added later. Rewiring drivers for each change is the usual cost of that flexibility. The Nucleo DALI DT6/DT8 power supply removes it: DALI digital bus, 0-10V analogue dimming, and manual push-dim are all wired into the same unit from the factory, so the control method is a commissioning decision, not a procurement one.
On the DALI side, the driver speaks both DT6 (single-channel brightness dimming) and DT8 (tunable white or RGBW colour control) — one product line covers plain white LED runs and full colour-tunable installs alike. The body stays constant voltage throughout, in 12V or 24V DC, purpose-built for LED strips and aluminium profile systems.
DT6 or DT8 — Which One Does Your Project Need?
Controls brightness (0–100%) of a single constant voltage LED load through one DALI address. The right choice for single-colour or plain white LED strip and profile runs where only dimming is required.
- Single output channel
- 0–100% smooth dimming
- One DALI address per unit
- Works with any standard DALI controller
- Available 12V & 24V, 60W–250W
Adds colour control on top of dimming. Drives tunable white loads (warm + cool white channels) or RGBW loads (four channels) from the same DALI bus. Needs a DT8-capable controller on the other end.
- 2-channel (tunable white) or 4-channel (RGBW)
- Brightness plus CCT or RGBW control
- Requires a DT8 DALI controller
- Available 12V & 24V, 60W–250W
- Suited to hospitality, retail, office fit-outs
Three Dimming Methods, Zero Rewiring
Every unit ships with all three control inputs already wired in — pick the one your project needs at commissioning:
Available Models & Wattages
Pick your output voltage and wattage based on the connected LED load and run length:
| Wattage | 12V DC | 24V DC | Max Load Current | DALI |
|---|---|---|---|---|
| 60W | ✓ Available | ✓ Available | 5A (12V) / 2.5A (24V) | DT6DT8 |
| 80W | ✓ Available | ✓ Available | 6.7A (12V) / 3.3A (24V) | DT6DT8 |
| 100W | ✓ Available | ✓ Available | 8.3A (12V) / 4.2A (24V) | DT6DT8 |
| 150W | ✓ Available | ✓ Available | 12.5A (12V) / 6.25A (24V) | DT6DT8 |
| 200W | ✓ Available | ✓ Available | 16.7A (12V) / 8.3A (24V) | DT6DT8 |
| 250W | ✓ Available | ✓ Available | 20.8A (12V) / 10.4A (24V) | DT6DT8 |
12V or 24V — which to choose? Use 12V DC for strip runs up to roughly 5 metres per channel, or where 12V-rated LED product is already specified. Use 24V DC for longer runs — up to ~10 metres per channel — to cut voltage drop and keep brightness even end to end; 24V also supports higher wattage per metre on strips of the same width.
Key Features
Sizing tip: add roughly 20% headroom above your calculated LED load rather than matching wattage exactly — a driver running close to its rated ceiling shortens its working life, while the extra margin keeps it comfortably loaded for the long run.
