In the LED display industry, the power distribution cabinet, as one of the core components, directly impacts the stability and lifespan of the display due to the high current surge during startup, caused by the large number of switching power supplies. Since LED displays are powered by high power, exceeding 10KW, it is essential to equip them with a dedicated intelligent power distribution cabinet for LED displays.

This product features an indoor housing with a total load power of 40KW, capable of connecting 12 single-phase electrical appliances (such as display loops, air conditioning loops, fan loops); it provides overcurrent and short-circuit protection, with step-by-step, graded power-on delay. It supports manual power on/off, remote automatic power-on via multi-functional cards, and power-off functions.
Features
1.All models feature dual protection; the input circuit breaker is a plastic-case circuit breaker, and the output circuit breaker is a miniature circuit breaker. 2. Supports multifunctional cards for remote intelligent control of the power system.
3.You can choose between manual or multi-functional card control for on/off and power cut functions.
4.Standard with overcurrent and short-circuit protection.
6.Manual, Stop, Automatic - three-position panel control switch.
7.Multi-channel step-by-step sequential power-on delay.
8.All critical components are made with renowned brand electronic components; all cables are selected from national standard copper cables, and all cables are terminated with pure copper terminals, with each cable having a 20% or more safety margin in diameter inside the box.
9. Products are designed and manufactured according to standard specifications, featuring unique reinforcement in the shell design and using sheet metal with a thickness of 1.2mm or more, then powder-coated.
10.All models come standard with circuit-breaker protected test sockets.
