FAQ
What type of LED driver is the Ltech DALI-15-150-700-F1A1?
The DALI-15-150-700-F1A1 is a 15W constant-current LED driver with DALI dimming control. It is designed for applications that need selectable output current within a single model rather than a fixed-current driver.
What output current range does this LED driver support?
This model supports selectable output current from 150mA up to 700mA. That makes it useful when matching different constant-current LED fittings while staying within the product's stated operating range.
Is this driver suitable for DALI dimming systems?
Yes, this model is built for DALI dimming and also supports Push Dim. It is designed for DALI-based lighting control projects, ensuring compatibility with standard DALI systems.
How smooth is the dimming performance on this model?
The product is specified with a 0 to 100% dimming range and a dimming depth of 0.01%. It is assessed as almost flicker-free under high frequency exemption, which helps on projects where very low dimming levels are important for visual comfort.
What environments is the DALI-15-150-700-F1A1 rated for?
This driver is rated for ambient temperatures from -20°C to 50°C. The description also states it is suitable for internal lights application, so it is intended for indoor use cases rather than exposed outdoor installation.
What protections are included in this LED driver?
The DALI-15-150-700-F1A1 includes overload, over-heat, and short-circuit protection with automatic recovery. These features are relevant for long-term reliability in commercial lighting applications.
