QLT Power Supply MN3 4.2W 12V 350mA for LED Modules

The QLT MN3 power supply — reference A40MN300000B — is a compact constant current LED driver, manufactured by QLT in white polycarbonate. Its slim profile — 59 mm in length, 42 mm in width and 20 mm in depth — allows effortless installation even in confined technical spaces. It delivers a constant output current of 350 mA at up to 4 W, with an output voltage range of 3–12 V, making it an excellent choice for powering LED modules that require a stable, consistent current supply. Insulation class II ensures a high level of electrical safety, while the IP20 protection rating restricts its use to indoor installations.

The universal input voltage, compatible with EU, AUD, USA, UK and JAP electrical standards across a range of 100–240 V AC, makes it suitable for international use. Self-resetting protection against overtemperatures, open circuit and secondary short circuits ensures consistent operation and long service life. The driver is not dimmable and must always be connected to LED modules with the same rated current, wired in series, in accordance with the technical installation guidelines.
