FAQ

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

A D4i / DALI-2 constant-voltage LED driver with a screw-free junction box built into the housing, 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-J at 12V / 6.67A (80W), MV-24096-D4I-J at 24V / 4A (96W) and MV-48096-D4I-J at 48V / 2A (96W). All are Class 2.

Q3: 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. Contact us for the termination detail if you need it for a submittal.

Q4: 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.

Q5: Does the wattage change the housing?

No. Every model from 30W to 96W uses the same housing, so the mounting footprint and cutout stay the same across the range and fewer spare parts are needed.

Q6: 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.

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.
