MX12300 Dimmable Constant Voltage LED Driver

12V DC Output, 300W, Phase Dimming Compatible

The MX12300 Dimmable Constant Voltage LED Driver is a high-capacity low-voltage power supply designed to provide stable 12V DC output for compatible LED lighting systems. According to the product label, this unit is a dimmable LED driver with phase dimming capability and is intended for use with forward phase and reverse phase dimmers, including ELV, MLV, and Triac dimmers. This makes it a practical solution for larger LED installations that require dependable dimming performance and consistent low-voltage power delivery.

Built as a constant voltage driver, the MX12300 accepts a wide 110–277V AC input range and converts it to 12V DC output, delivering up to 25A with a maximum power rating of 300W. This higher output capacity makes it well suited for applications requiring greater wattage support while maintaining stable 12V DC performance.

The product label states that this driver is suitable for dry, damp, and wet locations, offering flexibility for a range of installation environments when used properly and in accordance with applicable electrical codes. The unit is also marked Class P, Type HL, SELV, and RoHS, and it is cULus Listed. In addition, the label states that it conforms to UL 8750, CAN/CSA-C22.2 No. 250.13, and FCC requirements.

For wiring reference, the input side is labeled AC L (Black), AC N (White), and Ground (Green). The output side is marked LED + (Red) and LED – (Black). The label also specifies that for all connections, installers must use wire rated for at least 90°C (194°F).

The MX12300 is an excellent choice for projects requiring a 12V DC constant-voltage dimmable LED driver with broad dimmer compatibility, recognized compliance markings, and increased wattage capacity for larger low-voltage LED lighting applications.
