Frequently Asked Questions - ELG-150-12-3Y Mean Well
What is the input voltage range for the ELG-150-12-3Y?
The input voltage range is 100-277VAC at 47-63Hz. It can operate on both 120V and 240V mains.
How do I connect the dimming wires?
The dimming wires are typically blue (DIM+) and white (DIM-). Connect them to a compatible 0-10V dimmer, PWM controller, or a resistor (100kΩ potentiometer). Ensure the controller output is isolated.
Can this power supply be used outdoors?
Yes, the ELG-150-12-3Y has an IP67 rating, making it suitable for outdoor use, but it should not be submerged. It is resistant to dust and water jets.
What does the '3Y' suffix mean?
The '3Y' indicates that the power supply has 3-in-1 dimming functionality, supporting 0-10V, PWM, and resistance dimming methods.
How do I adjust the output voltage?
The output voltage is preset to 12V and is not user-adjustable. Use the dimming function to control brightness instead.
What is the efficiency of this power supply?
The efficiency is up to 87%, reducing heat generation and energy loss.
Can I connect multiple ELG-150-12-3Y units in parallel?
Yes, for higher current needs, you can connect them in parallel. However, ensure each unit's output current is balanced and do not exceed the total load limit. Mean Well recommends using a diode on each output to prevent reverse current.
What protection features does it have?
It includes short circuit, over load, over voltage, and over temperature protections. The power supply will automatically recover after fault conditions are removed.
What is the warranty period?
Mean Well offers a 5-year warranty from the date of manufacture. Keep the original invoice for warranty claims.
How do I install the power supply?
Mount it on a flat, heat-dissipating surface using the screw holes. Ensure adequate ventilation around the unit. Connect AC input wires to L/N/PE, and DC output wires to +V/-V. For dimming, connect DIM+/DIM- as per controller instructions.
