D4I UL Listed CV 30W-96W Linear Ultra-Slim D4i DALI-2 Dimmable LED Power Supply

Product Introduction

The SCPOWER MV-D4I-L Series is an ultra-slim linear 30W–96W ultra-slim linear constant voltage LED power supply with integrated D4i / DALI-2 digital control. Designed for compact lighting structures, it supports 120–277VAC input with active PFC and offers 12V, 24V and 48V output options. Available power ratings include 30W, 45W and 60W at each voltage, plus 80W at 12V, 96W at 24V and 96W at 48V. Its isolated Class 2 constant voltage output makes it suitable for a range of professional LED lighting applications.

D4i combines DALI-2 digital dimming with data feedback, allowing compatible commercial lighting management systems to communicate with and read driver information over the same bus. The series supports 0–100% PWM dimming and features short-circuit, overload and over-temperature protection, with fanless free-air convection cooling. It is designed to meet UL requirements and complies with FCC, Class 2, Class P, SELV, RoHS and REACH requirements for dry and damp locations. A 5-year warranty, OEM/ODM customization for electrical specifications and labeling, and sample availability before bulk orders provide added project flexibility.

FAQ

Q1: What is the MV-D4I-L Series?

A D4i / DALI-2 constant-voltage LED driver in a linear body, 30W to 96W, 120-277VAC input, 12V / 24V / 48V output, Class 2.

Q2: What models and power ratings are available?

30W, 45W and 60W in 12V, 24V and 48V. At the top of the range: MV-12080-D4I-L at 12V / 6.67A (80W), MV-24096-D4I-L at 24V / 4A (96W) and MV-48096-D4I-L at 48V / 2A (96W). All are Class 2.

Q3: What does D4i add over standard DALI-2?

Data feedback. A DALI-2 driver receives dimming commands; a D4i driver also lets the lighting system read data from it, so a commercial installation can be monitored rather than only controlled.

Q4: Why choose the linear version?

Because narrow slots, reveals and slim profiles cannot take a box beside the LED line. A linear body installs along the light line and remains concealed, so the fixture keeps its profile without a visible control enclosure.

Q5: Is it compatible with TRIAC or 0-10V dimming?

No — this series is D4i / DALI-2 only. For phase dimming or 0-10V / 1-10V / potentiometer control, use the MVG series.

Q6: How does it dim, and what protections does it have?

PWM dimming across a 0-100% range. Short circuit, overload and over-temperature protection, free air convection cooling with no fan.

Q7: Can I request samples before bulk ordering?

Yes. Samples are available for compatibility and performance testing before bulk orders.

Q8: What is the MOQ?

MOQ varies by model and customization requirements. Contact us for project-specific MOQ and pricing.

Q9: What certifications are available for shengchang (SCPOWER) LED power supply?

Shengchang (SCPOWER) offers a broad range of certifications across its LED power supply portfolio, including UL, cUL, ETL, FCC, CCC, RCM, SAA, ENEC, CE, CB, BIS, PSE, ICES-005, ErP, WEEE, DALI-2, D4i, Class 2, Class P, TYPE HL, UKCA, RoHS, REACH, and ISO 9001. Certification availability varies by product model, specification, and target market. Please contact us to confirm the certifications applicable to a specific product.
