FAQ
What type of lighting is the Ltech DALI-75-12-F1M1 designed for?
This model is a 75W 12VDC constant-voltage LED driver intended for indoor lighting applications that use DALI dimming and color temperature adjustment. It is built for tunable white systems where two independently SELV output channels are needed to control brightness and CCT together.
Is the DALI-75-12-F1M1 suitable for tunable white lighting control?
Yes. This driver supports DALI DT8 and is described as a DIM and color temperature adjusting driver with a 2700-6500K adjustment range. Its two independent constant-voltage output channels make it appropriate for tunable white LED lighting systems built around 12VDC operation.
What are the main electrical specifications of the Ltech DALI-75-12-F1M1?
The DALI-75-12-F1M1 is rated for 75W output at 12VDC with a rated current of 6.25A. It uses DALI dimming control, has a power factor >0.99 at 115Vac, and comes in a compact housing measuring 204×62×34mm.
How low can this DALI LED driver dim?
The DALI-75-12-F1M1 supports a 0-100% dimming range with a maximum dimming depth of 0.1%. It is also described as flicker-free across the 0-100% dimming range, which is useful where smooth low-level light control matters.
What makes this model different from a standard single-channel 12V LED driver?
Unlike a basic 12V constant-voltage driver that only provides power and dimming, this model adds DALI DT8 support plus color temperature adjustment. Its two independent SELV output channels are a key differentiator for tunable white applications rather than simple single-output dimming.
What operating conditions is the DALI-75-12-F1M1 rated for?
This driver is rated for operation from -30°C to 60°C and is described as suitable for indoor I/II/III type lamp applications. It also includes over-heat, overload, and short-circuit protection with automatic recovery.
