M-Series 300W 12VDC Magnetic Phase Dimmable LED Driver, 120V

Magnitude Lighting M-Series 300W LED Driver — 12V DC

M300L12DC is a Magnitude Lighting LED Driver rated 300W with 120VAC input and 12V DC Constant Voltage output for low-voltage LED lighting. It is phase dimmable using a leading (forward) edge MLV TRIAC dimmer only and is built in a coated metal housing with an Integrated Junction Box and multiple 7/8 in. knockouts. Protection is provided by primary and secondary manual reset circuit breakers.

Key Features

Physical Design & Installation

Coated metal enclosure in black with a built-in wiring compartment for line and low-voltage connections. The Integrated Junction Box includes multiple 7/8 in. knockouts and uses a 2-hole flange mount for secure mounting. Maintain 5 in. minimum installation spacing as specified by the manufacturer.

Dimming & Controls

Phase dimming is supported with a standard leading (forward) edge MLV TRIAC dimmer only. For accurate output verification, the manufacturer notes average voltage measurement should be taken with an oscilloscope (multimeters may read inaccurately). Minimum dimming level is 1%.

Performance & Build

Designed for 120VAC operation with a magnetic core constant voltage output stage. Primary and secondary manual reset circuit breakers provide protection for both the driver and connected LED load. Environmental rating is Dry & Damp.

Typical Applications

• LED tape and ribbon lighting
• LED tube lighting
• Linear LED lighting systems
• Residential and commercial low-voltage LED installations
