Key Specifications

The MEAN WELL LRS-150F-15 is a 150W enclosed single-output switching power supply that converts universal AC input (85 VAC to 264 VAC) to a regulated 15 VDC output at up to 10 A. Its miniature 1U low-profile enclosure measures 6.26 x 3.82 x 1.18 inches, making it well suited for space-constrained chassis and panel installations. Fanless free-air convection cooling supports quiet operation across a wide operating temperature range of -30°C to 70°C, and the unit carries agency approvals listed by MEAN WELL including UL, CUL, TUV, CB, CE, EN, EAC, and CCC.

Key Features and Benefits

• Universal AC input range (85 VAC to 264 VAC) with auto-switching - Supports use with a wide variety of AC mains voltages without manual adjustment, for compatible equipment.
• Fanless free-air convection cooling - Eliminates moving parts to support silent operation in noise-sensitive environments and helps reduce mechanical wear.
• Miniature 1U low-profile enclosure (6.26 x 3.82 x 1.18 inches) - Fits space-constrained chassis and rack installations where vertical clearance is limited.
• Built-in protections: short circuit, overload, over voltage, and over temperature - Helps safeguard connected equipment within the manufacturer's stated protection limits.
• 89% typical efficiency - Reduces heat dissipation and energy consumption at rated load.
• No-load power consumption <0.5 W - Helps minimize standby energy draw when the supply is energized but the load is disconnected.
• Withstands 300 VAC surge input for 5 seconds - Provides a degree of resilience against brief AC line transients, within the manufacturer's stated limits.
• Wide operating temperature range: -30°C to 70°C - Supports deployment in both cold-start and elevated-temperature industrial environments.
• Operating altitude up to 5000 meters - Supports installation in high-altitude locations, when installed according to the datasheet.
• Withstands 5G vibration test - Helps maintain mechanical integrity in vibration-prone industrial environments.
• LED power-on indicator - Provides a quick visual confirmation that the supply is energized.
• Screw terminal block output connector - Supports secure, tool-terminated wiring connections for industrial installations.
• Input isolation voltage: 3750 V minimum - Provides a high level of input-to-output isolation, supporting safety requirements in compatible equipment.
• Compliance to IEC/EN 60335-1 (PD3) and IEC/EN 61558-1, 2-16 for household appliances - Supports use in household appliance applications where these standards are required.
• 100% full-load burn-in test - Each unit is tested at full load before shipment, supporting consistent out-of-box reliability.
• 3-year manufacturer warranty - Provides extended coverage for long-term project and production deployments.

Customer Questions

Can this power supply run continuously at full load?

The LRS-150F-15 is rated for 150W continuous output (15 VDC at 10 A). It is cooled by free air convection and is rated for operation up to 70°C. Verify that adequate airflow is available around the unit and that ambient temperature and load conditions remain within the manufacturer's stated limits.

Does this power supply work with both 110V and 220V AC mains?

Yes. The LRS-150F-15 accepts universal AC input from 85 VAC to 264 VAC at 47 Hz to 63 Hz and switches automatically, so no manual voltage selection is required for compatible AC mains.

Does this unit include a cooling fan?

No. The LRS-150F-15 uses fanless free-air convection cooling. There are no moving parts in the cooling system, which supports quiet operation in noise-sensitive environments.

What protections are built into this power supply?

The LRS-150F-15 includes built-in short circuit, overload, over voltage, and over temperature protections, within the manufacturer's stated limits.

What certifications does this power supply carry?

Agency approvals listed by MEAN WELL for the LRS-150F-15 include UL, CUL, TUV, CB, CE, EN, EAC, and CCC. The unit also complies with IEC/EN 60335-1 (PD3) and IEC/EN 61558-1, 2-16 for household appliances. Refer to the datasheet and MEAN WELL compliance documentation for full details.

Customer Concerns

Will this supply fit inside my existing enclosure or panel?

The LRS-150F-15 measures 6.26 inches long by 3.82 inches wide by 1.18 inches tall (1U profile). Confirm that your enclosure provides sufficient clearance on all sides for free-air convection cooling, as the unit has no fan. Review the 3D outline drawing (available on the product page) and the datasheet for exact mounting hole locations and keep-out zones before installation.

Is 150W enough for my application, and can I run it at full load continuously?

The LRS-150F-15 is rated at 150W (15 VDC at 10 A). To confirm fit, calculate your total load current and verify it does not exceed 10 A. The unit is convection-cooled, so ensure ambient temperature and airflow conditions remain within the -30°C to 70°C operating range specified by the manufacturer. Derating may apply at elevated temperatures - consult the datasheet for the derating curve.
