The Mean Well LPV-20-5 delivers a regulated 5V DC output rated at 3A (15W maximum continuous output) across a universal input range of 90V AC to 264V AC. Engineered inside a fully encapsulated, flame-retardant plastic enclosure rated to IP67, this constant voltage LED driver withstands outdoor rain, dust, moisture, and temporary water immersion. While larger sibling models in the LPV series handle higher electrical loads—such as the 35W LPV-35-5, the 60W LPV-60-5, and the 100W LPV-100-5—the LPV-20-5 is optimized specifically for low-wattage accent lighting, micro-controllers, signage modules, and compact outdoor LED strip lighting runs. Designed as an isolated Class II power unit without need for an earth ground connection, it also complies with UL1310 Class 2 power unit safety regulations to protect downstream circuits against overcurrent, short circuits, and overvoltage events.
Fully potted internal electronics and an isolated plastic shell prevent moisture ingress and permit outdoor operation in damp, wet, and dusty locations.
Accepts 90V AC to 264V AC at 47Hz to 63Hz, allowing trouble-free operation across both 110V US/CA and 220V EU/UK/AU regional power grids.
Certified to UL1310 Class 2 power output limits and passes LPS (Limited Power Source) standards to minimize fire hazard and shock risks.
Measures 118 x 35 x 26 mm, allowing concealment inside narrow junction boxes, decorative sign channels, and architectural coves.
Includes automatic hiccup-mode short circuit and overload protection (110% to 150%) alongside zener-clamped overvoltage shutdown.
Withstands momentary input voltage surges up to 300V AC for 5 seconds without component breakdown or circuit failure.

Q: what is led power supply
A:An LED power supply is an electrical device that converts incoming alternating current (AC) line voltage into low-voltage direct current (DC) required to safely operate LED strip lights and fixtures.
Q: how to connect led strip lights to power supply
A:To connect an LED strip to a power supply, match the red positive wire from the power supply DC output to the +5V pad on the LED strip, and join the black negative wire to the -/GND pad on the strip, sealing the splice securely.
Q: how to connect led strips to power supply
A:Connect the incoming mains AC power to the driver input wires, then solder or fasten the driver 5V DC output leads directly to the copper solder pads on your LED strip, keeping cable runs under 3 meters to prevent voltage drop.
Q: how to connect the led strips to power supply
A:Check polarity on the LED strip marked + and -, connect them to the red (+5V) and black (-V) output wires of the LPV-20-5, and connect the input wires (Brown Live, Blue Neutral) to your AC electrical supply line.
Q: how to connect led lights to power supply
A:First verify that your LED light fixture requires 5V DC constant voltage. Connect the fixture positive terminal to the driver +5V output and negative terminal to the driver -V output, ensuring the fixture total wattage stays below 15W.
Q: are led light strips waterproof
A:Only LED strips manufactured with IP65, IP67, or IP68 silicone or polyurethane encapsulation are waterproof. Standard IP20 strips are for indoor dry use only, while an IP67 Water Resistant LED Strip is suitable for outdoor use.
Q: are led strip lights waterproof
A:Standard LED strip lights are not waterproof unless designated with an IP65, IP67, or IP68 rating. Always check the product ingress rating before installing strips in outdoor or high-moisture locations.
Q: how to install waterproof led strip lights
A:Mount the strip using outdoor-rated mounting clips or silicone adhesive channel, power it using an IP67 driver such as the LPV-20-5, and enclose all electrical wire splices in waterproof junction boxes.
Q: how to cut led strip waterproof
A:Cut only along the marked copper cut lines with sharp scissors, then seal the exposed raw edge using an outdoor silicone end cap filled with neutral-cure silicone sealant to maintain water protection.
Q: Why is the LPV-20-5 rated at 15W instead of 20W?
A:While other models in the LPV-20 family output 20W at higher voltages (12V, 15V, and 24V), the 5V model is limited by a 3A current ceiling, resulting in a maximum rated continuous output power of 15W (5V x 3A).
