Product Introduction
The LPV-150 series from Leyu is a 150W single-output waterproof switching power supply, specifically designed as a constant-voltage AC-DC power source for LED lighting and outdoor advertising signage. The unit features a fully sealed, potting-filled design with an insulating plastic housing, achieving an IP67 professional dustproof and waterproof rating, ensuring stable operation in both indoor and outdoor open-air environments.
It supports a wide AC input range of 180–305VAC, compatible with the grid voltages of most countries worldwide. Built-in surge protection withstands 300VAC high-voltage transients for up to 5 seconds, making it highly durable in outdoor thunderstorm conditions or areas with significant voltage fluctuations.
The series covers five mainstream DC output voltages—12V, 15V, 24V, 36V, and 48V—with a maximum rated power of up to 153.6W. Every unit undergoes 100% full-load burn-in testing before shipment, ensuring consistent and reliable quality. The product comes with a 2-year official warranty, offering a cost-effective power supply solution for bulk engineering procurement and outdoor lighting projects.
With a compact and space-saving design, the unit relies on natural air convection for cooling, eliminating the need for an additional fan and reducing potential failure points. Built-in short-circuit, overload, and overvoltage triple protection circuits automatically safeguard the system under abnormal load conditions; power is automatically restored once the fault is cleared, significantly reducing on-site maintenance and repair costs.

Comprehensive Protection, Safety, and Ease of Use
Fully encapsulated IP67 waterproof housing ensures reliable operation in damp, wet, or even rain‑exposed environments. Built‑in protections include short circuit, overload (110%–150% of rated power, hiccup mode with auto‑recovery), over‑voltage (output shutdown with power‑on reset required), and over‑temperature. Class II design eliminates the need for a functional ground (FG), simplifying and enhancing installation safety. The UL 94V‑0 flame‑retardant plastic enclosure adds an extra layer of safety.

High Reliability and Authoritative Certifications
Every unit undergoes 100% full‑load burn‑in testing before shipment to guarantee long‑term stability and reliability. Complies with UL8750, CSA C22.2, UL879, and IP67 standards, and is designed with reference to EN60950‑1, ensuring proven quality and performance.
Product Advantages
1. Excellent waterproof and dustproof performance
The LPV‑150 series is rated IP67 by an independent testing laboratory. The interior is fully potted with thermally conductive silicone, providing a complete seal. Whether outdoors in rain and snow, or in humid areas such as basements and bathrooms, the power supply operates reliably.
2. Wide‑range input for global use
Supports 180–305 VAC input, and can withstand 300 VAC surge for up to 5 seconds. No matter which country or region your project is in, this power supply can be used directly without any modifications.
3. High efficiency reduces operating costs
The series achieves efficiency up to 90%. For long‑running LED lighting installations, higher efficiency directly translates to lower electricity bills and reduced heat generation.
4. Comprehensive protections for safe operation
Four layers of protection: short circuit, overload, over voltage, and over temperature. Overload protection uses hiccup mode and automatically recovers when the fault is cleared; over voltage protection latches off and requires a power reset. These dual‑protection mechanisms give you peace of mind.
5. Fanless design for silent and durable operation
Heat is dissipated by natural convection, with no internal fan. This eliminates fan noise and removes a common failure point, significantly improving product lifespan and reliability.
6. Compact size, easy to install
Dimensions are only 191×37×37.5 mm (L×W×H), and weight is approximately 0.78 kg. The compact plastic case allows flexible installation without taking up much space.

FAQ
Q1: Can the LPV‑150 series be used outdoors?
Yes. The LPV‑150 series is rated IP67 and the unit is fully encapsulated, effectively preventing dust and moisture ingress. It is suitable for outdoor use in rain, snow, and humid environments.
Q2: Does this power supply require an external fan for cooling?
No. The LPV‑150 series uses a fanless natural convection cooling design. The interior is potted with thermally conductive silicone, which enhances heat dissipation and ensures stable operation over an ambient temperature range of –25 °C to +70 °C.
Q3: What happens if the power supply is overloaded?
The LPV‑150 series is equipped with overload protection (set at 110%–150% of rated power) that operates in hiccup mode. Once the fault condition is cleared and the load returns to normal, the output automatically recovers without any manual intervention.
Q4: What is the input voltage range?
The LPV‑150 series accepts 180–305 VAC input, 47–63 Hz, and also supports 254–431 VDC input. It can withstand a 300 VAC surge for up to 5 seconds.
Q5: What safety approvals does this power supply have?
The LPV‑150 series is approved to UL8750, CSA C22.2 No.250.13‑12, UL879, CSA C22.2 No.207‑M89, and is IP67 certified. The design also refers to EN60950‑1.
Q6: What is the difference between LPV‑150 and LPVL‑150?
The LPV‑150 has an input voltage range of 180–305 VAC and is available in five output models: 12V, 15V, 24V, 36V, and 48V. The LPVL‑150 has an input range of 90–132 VAC and is offered only in 12V and 24V versions. Both series share the same IP67 protection rating and Class II design.
