The MEAN WELL LPV-20-12 is a 20W single-output, constant voltage enclosed LED driver power supply rated at 12V DC and 1.67A. It accepts universal AC input from 90 to 264VAC at 47 to 63Hz, making it suitable for use across a wide range of AC mains environments. The unit is fully encapsulated to IP67 and cooled by free air convection, supporting LED lighting and moving sign applications where a compact, waterproof power solution is needed. Every unit undergoes a 100% full-load burn-in test at the factory per manufacturer practice.
Key Features and Benefits
Constant voltage design at 12V DC - Delivers stable output voltage within ±1.0% tolerance, helping maintain consistent brightness in LED lighting loads.
Universal AC input range: 90 to 264VAC, 47 to 63Hz - Supports a wide range of AC mains voltages without manual switching, simplifying installation across different electrical environments.
Fully encapsulated to IP67 - Helps protect internal components against dust ingress and temporary water immersion, supporting use in damp or outdoor-adjacent installations.
Protections: short circuit, overload, and over voltage - Built-in protection functions help safeguard connected LED loads within the manufacturer's stated limits.
Surge withstand: 300VAC for 5 seconds - Helps the supply tolerate brief AC line surges during installation or operation.
Cooling by free air convection - No fan required, supporting quiet operation and reducing mechanical wear points.
Class II power unit, no functional ground (FG) - Double-insulated construction eliminates the need for a protective earth connection, simplifying wiring in compatible installations.
UL1310 Class 2 power unit; Pass LPS - Meets Class 2 and Limited Power Source requirements, which may simplify downstream wiring compliance for compatible LED fixture installations.
Fully isolated plastic case - Provides electrical isolation between input and output, with a minimum isolation voltage of 3000V.
Output leads: stripped and tinned wire - Ready for direct wiring to terminal blocks or LED load connections without additional connector preparation.
100% full-load burn-in test - Each unit is tested at full load before shipment per manufacturer practice, supporting product reliability.
Compact enclosed form factor: 4.64 x 1.37 x 1.02 inches - Small footprint supports installation in space-constrained enclosures and sign cabinets.

Is the LPV-20-12 rated for outdoor or wet-location use?
The LPV-20-12 is fully encapsulated and carries an IP67 rating per the manufacturer datasheet, indicating resistance to dust ingress and temporary water immersion. Confirm that your specific installation environment and local code requirements are compatible with IP67-rated equipment before installation.
What AC input voltage does the LPV-20-12 accept?
The LPV-20-12 accepts universal AC input from 90 to 264VAC at 47 to 63Hz, covering both 120V and 240V mains systems without manual adjustment.
Does this power supply require a fan or forced-air cooling?
No. The LPV-20-12 is cooled entirely by free air convection. No fan is required. Ensure adequate airflow around the unit during installation per the manufacturer datasheet.
Does the LPV-20-12 require a ground connection?
The LPV-20-12 is a Class II power unit with no functional ground (FG) terminal. Double-insulated construction is used in place of a protective earth connection. Verify that your installation and applicable electrical codes permit Class II equipment before wiring.
What output connector type does the LPV-20-12 use?
Output leads are stripped and tinned wire, ready for direct connection to terminal blocks or LED load wiring without additional connector preparation.
Customer Concerns
Will this supply handle my total LED load without overheating?
The LPV-20-12 is rated for a maximum continuous output of 20W (12V at 1.67A). Size your LED load to stay within this rated power limit. The unit is cooled by free air convection, so ensure adequate clearance around the enclosure during installation as described in the manufacturer datasheet. Operating above rated load or blocking airflow may affect performance and longevity.
Is this power supply compatible with my LED strip or fixture?
The LPV-20-12 is a constant voltage supply designed for 12V DC LED loads. Confirm that your LED strip or fixture is rated for 12V DC constant voltage operation and that the total wattage of your load does not exceed 20W. Verify all compatibility and final equipment compliance requirements before installation.
