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.
WHAT'S INCLUDED:
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.
