D4I UL CV 30W-96W Ultra-Mini Linear Built-in Junction Box DALI-2 D4i Dimmable LED Driver

Product Introduction

The SCPOWER MV-D4I-JL Series is a 30W–96W constant voltage LED power supply integrating D4i / DALI-2 digital control, a linear aluminum housing and a built-in junction box. 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. Its isolated Class 2 constant voltage output supports a wide range of professional lighting applications. The integrated junction box keeps mains wiring within the driver housing, helping simplify fixture wiring and reduce separate installation components.

The Ultra-mini linear housing is designed to fit inside slim fixtures or along lighting profiles, making it suitable for mirror cabinets, display cases and light boxes. D4i combines DALI-2 digital dimming with data feedback, allowing compatible commercial lighting management systems to read driver information through the same bus. The series supports 0–100% PWM dimming, with built-in short-circuit, overload and over-temperature protection and 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 flexibility for lighting projects.

FAQ

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

A D4i / DALI-2 constant-voltage LED driver with a linear body and an integrated junction box, 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-JL at 12V / 6.67A (80W), MV-24096-D4I-JL at 24V / 4A (96W) and MV-48096-D4I-JL 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: What does the built-in junction box change on site?

Mains wiring terminates inside the driver housing, so there is no separate wiring box to mount beside it and no extra connection point on the fixture.

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.
