• Point-of-sale and small server peripherals

Key specifications

• Output voltage: 12V DC
• Maximum output power: 150W
• Single output configuration
• Enclosed metal housing suitable for cabinet or DIN-compatible mounting
• Regulated output with built-in protection features common to the LRS series

How to use

Install the Mean Well LRS-150-12 inside an appropriately ventilated cabinet or on a DIN-compatible mounting surface following local electrical codes. Connect the AC input according to the mains specifications and wire the 12V DC output to the load ensuring correct polarity. Confirm that the connected load does not exceed the 150W rating and allow adequate clearance around the unit for heat dissipation. Perform initial power-up checks to verify stable output voltage and that protection functions operate as expected under load conditions.

Usage recommendations

Use the power supply within its rated ambient temperature and ensure ventilation to avoid thermal shutdown. For long-term reliability, keep total load within the specified maximum and use proper fusing on the input side where required by installation standards. Match cable sizes to the load current to minimize voltage drop on the 12V output.
