2.3.4 Distribution Box for Rental LED Display
The distribution box for rental LED display is specifically designed for rental application.
The distribution box has features such as small size, light weight, quick installation and
maintenance, and is designed with truckles for easy movement and transportation.
The CEE standard compliant power plugs are used for the inputs and outputs. The
“stepwise delayed power-on” mode is used for the output to avoid instant impacts of
large load on the power grid. This can effectively protect the electronic elements in the
LED display and extend its lifespan. The multiple outputs, strong compatibility, and
high flexibility can realize quick power connection. The highly reliable and enclosed
cabinet can avoid direct contact with human body and effectively prevent foreign
objects. Protection against short circuit, overcurrent, overvoltage, overload,
overtemperature, and lightning is provided.
