Mean Well Switching Power Supply – 12VDC, 12.5A


Availability: In Stock


SKU: POW-018 Manufacturer: Mean Well Mfg Part Number: LRS-150-12 Category: Tags: , ,


This powerful 12V switching power supply from Mean Well is a replacement for the Mean Well NES-150-12 12.5A / 150W power supply we carried before. The LRS-150-12 does not accept 248-373VDC input like the previously carried model, but it does come in at a lower price and a much smaller form factor. The supply is capable of up to 12.5A output at 12VDC from a variety of common AC input ranges. The supply features a durable metal casing, short circuit protection, overload protection, and overvoltage protection.

The power supply can be easily mounted and features several mounting points. The input and output lines are connected using large screw terminals; to connect this power supply you will need an AC power cable – we offer two variants: An AC Power Plug to stripped wires or an AC power plug with terminal fork leads.

The correct input voltage range does need to be set manually with this power supply – this can be done with a large selector switch inside the metal case and needs to be done before the supply is connected. The available input ranges are: 85VAC to 132VAC and 176VAC to 264VAC. The output voltage is adjustable using a trim potentiometer next to it’s inputs/outputs. The output voltage can be adjusted between 10.2 and 13.8VDC. The power supply can operate in air temperatures between -30°C to +70°C and only requires passive cooling. If you need a lot of reliable power, these are a great choice!

Please Note: This power supply uses mains voltage that is exposed on open connectors. It should only be used with those experienced in handling high voltage.
