300W power for large LED runs: Converts 120VAC to 12V DC at up to 300 watts (25 amps) for extensive single-color strip lighting circuits.
Magnetic MLV TRIAC dimming: Magnetic low-voltage driver engineered for smooth 0–100% phase-cut dimming with compatible wall dimmers.
ETL listed, 6-year warranty: ETL safety listing and a 6-year warranty support demanding residential and commercial projects.

PRODUCT DETAILS:

This 300 watt M-Series dimmable driver from HitLights is a high-capacity magnetic power supply that converts 120V AC input (108–132VAC, 50/60 Hz) to regulated 12V DC for single-color 12V LED strip lights. It is sized for large kitchens, long coves, shelving systems, and commercial displays where multiple or long runs are controlled from a standard wall dimmer.

The driver delivers 12V DC output at up to 300 watts, or 25 amps, with a power factor of 0.96 and a wide 0–100% dimming range. A magnetic core and phase-dimmable design support magnetic low-voltage (MLV) TRIAC dimmers from brands such as Lutron and Leviton, helping to reduce flicker and dropout when dimming LED strip loads.

A coated metal enclosure rated NEMA 3R for dry and damp locations houses the driver, with bare wire leads for line, neutral, ground, and low-voltage outputs. The housing measures approximately 89 x 249 x 107 mm (3-1/2 x 9-7/8 x 4-3/16 inches) and weighs about 8.75 lbs, suitable for junction box or utility-space installation. Integrated primary and secondary circuit protection with resettable breakers adds overload and short-circuit protection.

Unlike plug-in or non-dimmable power supplies, this M-Series driver is designed specifically for forward-phase dimming of permanent LED strip installations, allowing one high-capacity driver to replace multiple smaller supplies in large layouts.

FREQUENTLY ASKED QUESTIONS:

Q: What is the 12V 300W M-Series dimmable driver used for?
It is a 300-watt magnetic dimmable LED driver that converts 120V AC to 12V DC for powering extensive single-color 12V LED strip light runs indoors. Typical applications include long under-cabinet runs, continuous coves, display lighting, and larger commercial or residential linear lighting projects that need wall-dimmer control.

Q: Who is this 300W magnetic driver designed for?
This model suits electricians, low-voltage contractors, lighting designers, and advanced DIY users who prefer a single, high-capacity supply powering multiple 12V strip circuits. The 300W rating and 12V output give headroom for long or multi-zone installations where a compact magnetic driver is preferred over several smaller supplies.

Q: How does the driver work with wall dimmers?
The driver connects to 120VAC through a compatible magnetic low-voltage TRIAC wall dimmer, then provides a dimmed 12V DC output to the LED strips. It is designed for forward-phase (MLV) dimming and is compatible with many Lutron and Leviton dimmers listed in the M-Series documentation, allowing smooth 0–100% brightness control when the load is correctly sized.

Q: What are the key electrical and physical specifications?
Input is 120VAC (108–132VAC), 50/60 Hz. Output is 12V DC up to 300W, or 25A, with a power factor around 0.96 and high typical efficiency for the 12V version. The enclosure is a black, coated metal housing roughly 89 x 249 x 107 mm and about 8.75 lbs, rated NEMA 3R for dry and damp indoor locations.

Q: How does this 300W driver compare to smaller or non-dimmable supplies?
Multiple small plug-in or non-dimmable supplies are not intended for phase-cut dimming and can flicker or shut down with wall dimmers. This 300W M-Series unit is purpose-built for MLV TRIAC dimming, combining magnetic design, a wide dimming range, resettable protection, and ETL listing to support large permanent installations with a single driver.

Q: What is included, and what accessories are needed?
The package includes the 300W M-Series magnetic driver with bare wire leads for AC line, neutral, ground, and low-voltage outputs. LED strip lights, dimmer switches, junction boxes, connectors, and mounting hardware are selected separately to match the project’s layout, load, and code requirements.

Q: Can this driver be used outdoors, with RGB, or with COB strip lights?
This model is rated NEMA 3R for dry and damp locations and is intended for indoor use; waterproof power supplies are recommended for exposed outdoor environments. It is designed for single-color 12V LED strip lights and is not a controller for RGB or COB strips, which require dedicated multi-channel control hardware.

Useless

These will not secure the wire. Even slight pressure will pull the wire loose. Basically useless

Hi David,

Great Connectors!

These connectors are very well made. The screw mechanism also feels solid when you attach the wires or the light strips.

The screw driver is a little on the cheap side, but since that is not part of the connectors I am still rating the connector 5 stars; I just use my own screwdriver.

The thing I cannot figure out is what the little adhesive stickers are for. I THOUGHT they were to attach the connector, but the stickers only have adhesive on one side, that is, they are not double sided adhesive. See photo.
If you peel the sticker that says "3M" off it is sticky on one side. Once you peel the "3M" sticker off one side underneath there is a white slick paper (no adhesive). You flip that over and the other side is brown and say "3M". You peel that off it is also sticky on one side and you are left with the OTHER side of the white slick paper (no adhesive on this side either). So what you have is a total of three pieces once you have finished peeling everything off. Two pieces that say "3M" and are sticky on side, and one piece that is white and slick paper with no sticky on either side.

None of these items are double sided adhesive, so if someone can tell me what they are for I would appreciate it.

Great experience love the product.
