LED power supply ELG-150-12A-3Y, 120W 12V 10A

Universal switching power supply for LED lighting

This switching power supply from MEAN WELL, model ELG-150-12A-3Y, is a reliable solution for powering various LED lighting installations. It provides a stable output voltage of 12V with a current of 10A, offering a power of up to 120W. Thanks to the use of active PFC (Power Factor Correction), it minimizes interference in the electrical network and increases energy efficiency.

This power supply is particularly recommended for both professional installers and end-users looking for an efficient and safe solution. Its compact dimensions (219x63x35.5mm) make it easy to install in limited spaces, and its high efficiency (88%) translates to lower operating costs.

Safety and functionality

The power supply design has been enhanced with a number of protections that protect both the unit itself and the devices connected to it. These include:

• Overload protection: automatically shuts off the power supply if the permissible power is exceeded.
• Overheat protection: protects against damage caused by excessively high operating temperature.
• Overvoltage protection: stabilizes the output voltage, protecting sensitive LED components.
• Short-circuit protection: immediately cuts off the power supply in the event of a short circuit in the circuit.

Additionally, the CV+CC function (constant voltage and constant current) allows for flexible adaptation of the power supply to different types of LED loads, which increases its versatility. Active PFC improves the power factor, which is particularly important in larger installations, where it can affect the stability of the electrical network.

Installation and application

The ELG-150-12A-3Y power supply is widely used in:

• LED lighting: LED strips, LED panels, LED spotlights, LED downlights
• Advertising lighting systems
• Lighting installations in residential and commercial buildings
• Industrial applications requiring stable LED power

The cable length of 300mm provides convenience during connection to the electrical installation. The output voltage tolerance is +/-3%, and the ripple level is 150mV – these parameters guarantee stable and reliable operation of the device.
