Power Supply Unit MEAN WELL LRS-150-24

The MEAN WELL LRS-150-24 is a compact 156 W metal enclosed power supply that delivers a 24 V DC output. It accepts an AC input range selectable by switch, covers 85–132 Vac at 47–63 Hz, and withstands surge inputs up to 300 VAC for 5 seconds. The unit features a 1U low profile (97 × 159 × 30 mm), low no-load power consumption (<0.5 W), LED power-on indicator, and is designed for operation up to 70°C and at altitudes up to 5000 m. Built-in protections include short circuit, overload, over voltage and over temperature. The LRS-150-24 complies with household and equipment safety standards such as IEC/EN 60335-1 (PD3) and IEC/EN 61558-1/-2-16, and is tested for vibration and full-load burn-in to ensure long life and reliability.

Advantages

The LRS-150-24 combines a small metal housing and 1U low profile for space-constrained installations with high efficiency and a long MTBF for reliable continuous operation. It offers multiple safety protections, an LED power indicator, and a low standby power draw. The design tolerates high ambient temperature (up to 70°C), high-altitude operation, and a 300 VAC surge for short durations, making it suitable for demanding environments while meeting relevant safety standards.

Suitable for

• Industrial control systems and automation equipment
• Household appliance interfaces that require certified power supplies
• Embedded systems and communication devices with 24 V input
• Installations in cabinets or panels with limited depth and low-profile requirements

How to use

Install the LRS-150-24 on a flat mounting surface or inside an enclosure with adequate ventilation for free air convection cooling. Select the appropriate AC input range using the built-in switch before applying mains power. Connect the AC input and the 24 V DC output following wiring diagrams and polarity markings; observe local electrical codes and safety practices. Ensure the unit is mounted so that air can circulate around the housing and that ambient temperature limits and altitude ratings are not exceeded.

Usage recommendations

Place the power supply in a ventilated location, avoid covering ventilation openings, verify the input selector position matches your mains voltage, and provide appropriate fusing at the AC input. For installations exposed to vibration or extreme conditions, confirm mounting and connections meet site requirements and periodic inspection is carried out.
