The dimmable driver that disappears into the build
A slim constant voltage power supply that fits inside the profile or ceiling void, and takes DALI, 0-10V or push-dim from the same unit.
Space is tight and the control spec keeps changing
On site, two things go wrong with LED drivers. The driver is too bulky for the cavity the electrician was promised, and the control system gets decided late: a BMS integrator wants DALI, the client prefers a wall dimmer, or one zone moves to 0-10V.
This Nucleo power supply answers both. The body is slim enough to sit inside aluminium profile channels, ceiling voids and trunking. All three dimming inputs are built into the unit, so the control method is a wiring decision at commissioning rather than a purchase decision months earlier.
Constant voltage, by design
Output is fixed at 12V or 24V DC within the rated wattage. That makes it the right choice for LED strips, profile systems and other fixed-voltage loads. For COB modules and spotlights, specify a constant current driver instead.
DT6 for brightness, DT8 for colour
DALI DT6 · single channel
One DALI address controls brightness from 0 to 100% on a single-colour or white load. Works with any standard DALI controller.
- Best for white strip and profile runs
- Simple addressing and commissioning
- 12V and 24V, 60W to 250W
DALI DT8 · tunable white / RGBW
Adds colour control on the same bus: two channels for tunable white, four for RGBW. Needs a controller that supports the DT8 colour extension.
- Best for hospitality, retail and offices
- Brightness and colour from one address
- 12V and 24V, 60W to 250W
Three control inputs, one unit
DALI for addressed, scene-based commercial control. 0-10V for analogue dimmer panels, KNX modules and BMS outputs. Push-dim for a simple two-wire button, where holding the button ramps brightness up or down with no controller at all.
Built for concealed installation
Ultra-slim body
Slides into profile channels, false ceiling voids and recessed trunking where a brick driver will not fit.
DALI-2 digital bus
Addressing, groups and scenes for commercial projects, on both DT6 and DT8 variants.
Smooth, flicker-free dimming
Full 0 to 100% range without visible steps at the low end.
Full protection
Short circuit, overload, over-voltage and over-temperature protection with automatic recovery.
Fanless cooling
Convection cooled, so there is no fan noise or moving part to fail in a quiet room.
Power factor above 0.90
Efficient use of supply, with wide AC input from 100 to 240V.
Change control later
Move from push-dim to DALI, or add a BMS, without replacing the driver.

Sizing in three moves
Add up the strip wattage. Add about 20% headroom. Round up to the next unit. Choose 24V for runs up to about 10 metres per channel and 12V for runs of about 5 metres or where 12V strip is already specified.
