The MEAN WELL LRS-600-48 is a 600W enclosed single-output AC-to-DC switching power supply delivering 48 VDC at up to 12.5 A. It features a switch-selectable AC input range covering 90 VAC to 132 VAC or 180 VAC to 264 VAC, making it suitable for use with a wide range of facility power configurations. The 1U low-profile enclosure incorporates a built-in fan with ON-OFF control for forced-air cooling, and the unit carries agency approvals listed by MEAN WELL including UL, CUL, CB, CE, EAC, UKCA, AS/NZS, and IEC/EN 61558-1. A 3-year warranty is included.
Key Features and Benefits
Switch-selectable AC input range (90-132 VAC or 180-264 VAC) - Supports two common facility voltage standards without requiring a separate power supply for each environment, when the correct range is selected before installation.
Withstands 300 VAC surge input for 5 seconds - Helps the supply tolerate brief AC line transients within the manufacturer's stated limits.
Built-in protections: short circuit, overload, over voltage, over temperature - Helps protect the supply and connected equipment under abnormal operating conditions, within the manufacturer's stated limits.
Forced-air cooling with built-in fan ON-OFF control - Actively manages internal temperature to support reliable operation across the rated temperature range, while the ON-OFF control reduces fan noise and wear during lighter loads.
1U low-profile enclosure (1.61 inches height) - Fits standard 1U rack or panel spaces, supporting compact system designs.
High operating temperature up to 65°C - Supports deployment in warm industrial environments within the manufacturer's stated derating guidelines.
Operating altitude up to 5000 meters - Supports installation in high-altitude facilities within the manufacturer's stated limits.
Withstands 5G vibration - Helps maintain mechanical integrity in environments with moderate vibration, such as industrial machinery.
92% typical efficiency - Reduces heat dissipation and energy consumption relative to lower-efficiency designs.
Screw terminal block output connection - Supports direct hardwired connections to load equipment without requiring proprietary connectors.
MTBF greater than 1,500,000 hours - Indicates a high calculated reliability figure per the manufacturer's stated methodology.
3-year manufacturer warranty - Provides documented coverage for the product after purchase.
MEAN WELL patented circuitry and case design (Application #: 202220241473.0, 202230060511.8) - Reflects proprietary engineering in the mechanical and electrical design of this series.

Does the LRS-600-48 support both 115V and 230V AC input?
Yes. The input voltage range is switch selectable between 90-132 VAC and 180-264 VAC. Confirm the correct range is set for your facility before installation, as described in the product datasheet.
What output voltage and current does this supply provide?
The LRS-600-48 provides a single regulated output of 48 VDC at up to 12.5 A, for a total rated output power of 600W.
How is the unit cooled?
The LRS-600-48 uses forced-air cooling with a built-in fan. The fan includes an ON-OFF control that activates based on thermal demand.
What protections are built into this power supply?
The LRS-600-48 includes built-in protection for short circuit, overload, over voltage, and over temperature conditions, within the manufacturer's stated limits.
What agency approvals does the LRS-600-48 carry?
Agency approvals listed by MEAN WELL for this product include UL, CUL, CB, CE, EAC, UKCA, AS/NZS, and IEC/EN 61558-1. Refer to the MEAN WELL compliance documentation for full details.
Customer Concerns
I need to verify the supply will fit in my enclosure or rack space.
The LRS-600-48 measures 8.86 inches long by 4.88 inches wide by 1.61 inches high (1U low profile). Confirm these dimensions against your enclosure or rack cutout before ordering. The datasheet includes a mechanical drawing for precise fit verification.
I am not sure whether this supply can handle my load at elevated ambient temperatures.
The LRS-600-48 is rated for operation from -20°C to 65°C. Power supplies in this class are typically subject to output derating at higher ambient temperatures. Consult the MEAN WELL datasheet for the derating curve applicable to your installation to confirm the supply can deliver your required load at your operating temperature.
I want to confirm the input voltage switch is set correctly before powering on.
The AC input range must be set with the selector switch before connecting to mains power. Selecting the wrong range for your facility voltage can result in improper operation. Refer to the installation instructions in the MEAN WELL datasheet to verify the correct switch position for your input voltage.
