DALI-2 UL CV 30W-96W Linear Ultra-Slim Dimmable LED Power Supply

Product Introduction

The MV-DA-L Series is a ultra-slim linear constant voltage LED power supply with built-in DALI-2 digital dimming, designed for ultra-slim aluminum profiles, light boxes, menu boards and cove lighting. Featuring a compact linear aluminum housing, it fits inside fixtures or along lighting profiles rather than requiring separate installation space beside them. With 120-277VAC input and active PFC, it offers 12V, 24V and 48V output options, including 30W, 45W and 60W models at each voltage, plus 80W at 12V and 96W at 24V or 48V.

The series supports DALI-2 digital control with 0-100% dimming and isolated Class 2 / SELV constant voltage output. Built-in short-circuit, overload and over-temperature protection, together with fanless natural convection cooling, supports reliable operation. It is UL Standard and FCC compliant, with Class 2, Class P, SELV, RoHS and REACH compliance for dry and damp locations. A 5-year warranty, OEM/ODM customization for electrical specifications, labeling and sample availability before bulk orders provide added flexibility for lighting manufacturers and project requirements.

FAQ

Q1: What is the MV-DA-L Series?

The MV-DA-L Series is a constant voltage LED power supply with DALI-2 digital dimming, featuring a slim linear aluminum housing. It offers 30W–96W power options, 120–277VAC input, and 12V, 24V, or 48V output for slim fixtures and light boxes.

Q2: What models and power ratings are available?

The series offers 30W, 45W, and 60W models in 12V, 24V, and 48V versions. Higher-power options include MV-12080-DA-L (12V/6.67A, 80W), MV-24096-DA-L (24V/4A, 96W), and MV-48096-DA-L (48V/2A, 96W). All models feature Class 2 output.

Q3: What are the benefits of DALI-2 dimming?

DALI-2 enables digital lighting control through a DALI-2 bus system, allowing individual driver addressing and centralized lighting management. The series supports a 0–100% dimming range for flexible brightness adjustment.

Q4: Is the MV-DA-L Series compatible with TRIAC or 0-10V dimming?

No. The MV-DA-L Series supports DALI-2 digital dimming only. For TRIAC, 0-10V, 1-10V, or potentiometer dimming, consider the MVG Series.

Q5: Why choose a linear LED power supply?

The ultra-slim linear aluminum housing is designed for light boxes, menu boards, and slim aluminum profiles where installation space is limited. It fits neatly inside fixtures or along lighting runs, helping create a cleaner and more integrated installation.

Q6: What protection features and cooling method does it offer?

The series features short-circuit, overload, and over-temperature protection. It uses natural air convection cooling without a fan, making it suitable for enclosed lighting installations where quiet, fanless operation is preferred.

Q7: Where can it be installed?

It is suitable for dry and damp locations, with isolated Class 2 / SELV output. For wet locations, contact us to confirm a suitable IP-rated model.

Q8: What certifications, warranty and customization are available?

The series carries UL, FCC, Class 2, Class P, SELV, RoHS, and REACH certifications and compliance, with a 5-year warranty. OEM/ODM customization covers electrical specifications and labeling. Samples are available for approval before bulk orders.
