Features:

1.This is an ultra-thin switching power supply specifically designed for LED light boxes, flexible film light boxes, and long LED strips. It features a narrow, elongated body and active heat dissipation, making it a dedicated solution for light boxes.
2. It uses an aluminum alloy profile shell with a long, ultra-thin design, making it lightweight and aesthetically pleasing. Specifically designed for the limited installation space of light boxes and their profiles, it can be directly embedded inside the light box profile without taking up extra space, resulting in a cleaner installation. It solves the pain point of traditional power supplies being bulky and difficult to fit.
3.Circuit Protection: The LED power supply has overvoltage, overload, and short-circuit protection, ensuring safe and reliable operation and high practicality.
4.Terminal Design
- Input Terminals: High-current terminals with transparent protective covers, clearly marked with L (live), N (neutral), and ground symbols, ensuring safe and clear wiring and capable of handling AC input current.
- Output Terminals: Multi-pin terminals facilitate parallel wiring of multiple LED strips/strips, adapting to the power supply needs of multiple light sources within a light box.
5. This DC 12V 400W ultra-thin LED light box power supply is widely used in LED linear lights, light strips, and main light-less lighting systems; store sign soft film light boxes, fabric light boxes, long LED light strips, LED lighting systems for shopping malls, subways, and advertising light boxes, etc.
