"500*1000 network" – a series of LED rental displays – has several prominent features. The box’s modular design: power supply receiving cards and others can be independently plugged. The cabinet's power supply can be maintained during outage, not affecting the other boxes’ normal operation. Multi-function fast lock connection: self-lockable, fast, convenient and simply connected and slightly adjusted. The box’s anti-collision convex platform design protects the module during packaging, transport and placement. The design of the box’s side lock allows splicing any arc from -15º to 15º. Thanks to a long handle with plastic sleeve it is easy to operate.
