UL CV 120W-384W Ultra-Mini Triac 0-10V 5-in-1 Linear Built-in Junction Box Dimmable LED Power Supply

Product Introduction

The SCPOWER MVG-C-DW-JL Series is a ultra-mini constant voltage dimmable LED power supply with a linear housing and integrated junction box. Available in six power ratings from 120W to 384W, it supports 12V, 24V and 48V isolated Class 2 / SELV outputs. Its linear design fits neatly into coves, linear fixtures and concealed joinery spaces, while the built-in junction box simplifies wiring without requiring a separate enclosure.

With 120-277VAC input and active PFC, the series supports TRIAC/MLV, ELV, 0-10V, 1-10V, 10V PWM and potentiometer dimming options. It provides a 0-100% dimming range, 0.1% dimming depth and 15% minimum load. Built-in short-circuit, overload and over-temperature protection, together with fanless natural convection cooling, supports reliable operation. UL Standard, FCC compliance, Class 2 / Class P / SELV ratings, RoHS and REACH compliance, and a 5-year warranty make it suitable for hospitality and commercial lighting projects.

FAQ

Q1: What is the MVG-C-DW-JL Series?

The MVG-C-DW-JL Series is a multi-channel constant voltage dimmable LED power supply featuring a linear housing and built-in junction box. It is designed for hospitality, cove and linear lighting applications.

Q2: What power and voltage options are available?

The series offers 120W, 180W, 192W, 240W, 288W and 384W models, with 12V, 24V and 48V constant voltage outputs and isolated Class 2 / SELV protection.

Q3: What is the difference between the MVG-C-DW-JL and MVG-C-DW-J Series?

Both series share the same electrical platform, but feature different housing designs. The JL Series uses a linear housing for installation along coves or inside linear fixtures, while the J Series features a rectangular housing.

Q4: What are the advantages of the built-in junction box?

The built-in junction box eliminates the need for a separate wiring enclosure, helping simplify installation and save space in ceiling voids, coves and other concealed locations.

Q5: Which dimming methods are supported?

It supports forward-phase TRIAC, MLV, reverse-phase ELV, 0-10V, 1-10V, 10V PWM and potentiometer dimming options.

Q6: Does the series support smooth dimming?

Yes. It supports 0-100% dimming, 0.1% dimming depth and a 15% minimum load for flexible lighting control. Actual performance depends on the dimmer and installation conditions.

Q7: Is the MVG-C-DW-JL Series suitable for enclosed cove installations?

The series is rated for dry and damp locations and uses fanless natural convection cooling. Adequate airflow around the housing is required. Fully sealed spaces should be ventilated or provide sufficient cooling clearance.

Q8: What certifications, warranty and customization services are available?

The series offers UL, FCC, Class 2, Class P, SELV, RoHS and REACH certifications or compliance, depending on the model, with a 5-year warranty. OEM/ODM services cover electrical specifications, wiring, labeling and face plate customization. Samples are available for evaluation before bulk orders.
