Key product features
💡 Semi-filled adhesive protection design
Only the core circuit area is sealed with glue, while the heat sinks and interfaces remain open. This design provides moisture-proof, rain-proof, and corrosion-resistant protection while maintaining efficient heat dissipation. Compared to ordinary three-proof paint power supplies, it offers higher protection levels; even a small amount of water intrusion can still allow normal operation, significantly reducing failure rates in outdoor use.
💡 Stable power supply performance
A forced air cooling system is used to ensure stability during full load operation; it features multiple protection functions such as overvoltage, overcurrent, short circuit, and overload protection. It can still provide a stable 24V DC output even during voltage fluctuations, making it suitable for complex outdoor electrical environments.
💡 Designed for demanding outdoor environments
The all-aluminum casing features rust prevention and anti-aging properties, allowing it to operate reliably over the long term in harsh environments such as damp areas, coastal regions, and tunnels. It has been optimized for durability specifically for outdoor engineering applications.
Applicable Scenarios
This power supply is primarily used for various outdoor lighting projects, including:
– Advertising signs, illuminated characters, and power supply for billboards
<t_XXXXXXXXX> <t_XXXXXXXXX>
- Building facades, bridges, tunnels, outdoor landscape lighting projects
<t_XXXXXXXXX> <t_XXXXXXXXX>
- Scenarios requiring outdoor power supply for outdoor security surveillance, outdoor LED light strips/light boxes, etc.
Tips for installation and use
When installing outdoors, it is recommended to secure the connections with the terminals facing down to prevent rain from directly entering the connections; also, ensure there is sufficient heat dissipation space, and do not block the top heat dissipation and ventilation openings to maintain effective heat dissipation.
