Tápegység MEAN WELL LRS-150F-12

The MEAN WELL LRS-150F-12 is a 150W enclosed signal-output power supply with a 30 mm low-profile metal mesh casing. It accepts a wide AC input range of 85–264 VAC and provides a stable 12V output. The stainless-steel construction and enhanced ventilation allow the unit to operate from -30°C to 70°C under natural convection without a fan, while maintaining high efficiency up to 90% and very low no-load power consumption (under 0.5W).

Advantages

The LRS-150F-12 combines compact dimensions (159 × 97 × 30 mm) and a metal mesh case for improved heat dissipation, offering reliable operation in harsh environments. It includes complete protection features (overvoltage, overload and short circuit) and meets multiple international safety standards including UL60950-1, TUV EN60950-1, EN60335-1, EN61558-1/-2-16 and GB4943. The unit supports operation up to 5000 m altitude and has 5G anti-vibration capability.

How to use

Install the LRS-150F-12 in a location that allows free air circulation around the metal mesh case to ensure proper heat dissipation. Connect the AC input to a mains supply within 85–264 VAC, observe correct polarity on the 12V output terminals, and secure all wiring according to local electrical codes. Verify load requirements do not exceed 150 W and allow the unit to cool naturally; no fan is required. Use appropriate fusing and grounding as part of the system installation.

Recommendations

For reliable long-term operation, avoid enclosing the power supply in tightly sealed compartments and ensure a minimum clearance around the unit for airflow. When used at high altitudes or elevated ambient temperatures, check thermal derating and system ventilation to maintain safe operating conditions.
