Constant voltage power supplies: 12V, 24V and 48V DC

Constant voltage power supplies at 12V, 24V and 48V DC are designed for LED strips and LED modules driven by direct voltage. They are the standard solution for most decorative installations, from indirect lighting systems under cabinets and furniture, to aluminum profiles for false ceilings and stair markers, up to architectural backlighting applications.

Constant current power supplies for LED modules and chips

Constant current power supplies with variable voltage are designed for LED modules and chips driven by current, with typical values of 350mA, 500mA, 700mA and 1000mA. They are essential in professional applications where the stability of the luminous flux and the lifespan of the LED depend on maintaining a constant driving current.

How to choose the right LED power supply

To choose the right constant voltage power supply, simply check the operating voltage of the installed LED strip or module and calculate its total power consumption in watts, adding a 20% safety margin.

For constant current power supplies, you need to check the number of LED modules or chips connected in series and select the appropriate driver. A practical example: with 4 LED modules of 350mA and 1W each, with a single operating voltage of 3.2-3.4V, you will need a power supply with a constant output current of 350mA and an operating voltage of at least 3.4V × 4 = 13.6V.

Presence and brightness sensors for LED profiles

Proximity and brightness sensors for LED profiles are installed directly inside the aluminum profile, support a load of up to 2A, and allow the adjustment of intervention times. They are the ideal solution for creating automatic lighting under cabinets, in wardrobes, display cases, shelving units, and passageways, ensuring automatic switching on and off upon motion detection or based on ambient light.

Control units for RGB LED strips

RGB LED strip control units are equipped with radio frequency remote controls, which guarantee reliable operation even in the presence of walls, obstacles, or objects placed between the remote control and the receiver. Unlike infrared systems, radio frequency does not require direct pointing of the receiver, allowing the system to be controlled even from adjacent rooms.

Why choose Mean Well

Mean Well has been the international reference point for decades for those seeking professional-quality LED power supplies and drivers. Mean Well products are certified according to the main international standards (CE, TÜV, UL, CB, RoHS), offer complete protection against overvoltage, overcurrent, short circuit, and overtemperature, and are covered by extended warranties that testify to their construction reliability.
