In the LED display industry, the power distribution cabinet, as one of the core components, directly affects the stability and lifespan of the display due to the large amount of switching power supplies required. With the screen's startup瞬间, the current is high, easily impacting the power grid. Therefore, for displays with power over 10KW, a dedicated intelligent power distribution cabinet for LED displays should be provided.
This product features an indoor housing with a total load power of 140KW, capable of connecting 42 single-phase electrical equipment circuits (such as display loop, air conditioning loop, fan loop). It offers overcurrent and short-circuit protection with step-by-step, graded delay in power-on. It supports manual power on/off, remote automatic power on/off with a multi-functional card, and power off function. The standard circuit breaker is a Delixi product, while the contactor is a Schneider product. The multi-functional card power supply uses Mingwei's high-reliability industrial-grade products to ensure stable system power supply.
Key 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.Choose between manual or multi-functional card control for on/off operations.
4.Standard with overcurrent and short-circuit protection.
5.Different color sequence power indicator lights differentiate the phase line power-in status.
6.Manual, Stop, Automatic, three-position panel control toggle switch.
7.Sequential step-by-step power-on with multi-channel delay.
8.All critical components are made with internationally renowned brand components; cables are all selected from national standard copper cables, and all cables are terminated with pure copper terminals, with each cable inside having a safety margin of over 20%.
9. Products are designed and manufactured in accordance with national standards, featuring unique reinforcement in the housing design and made from sheet metal with a thickness of 1.2mm or more, then powder-coated.
10.All models come standard with circuit breakers for inspection sockets and lighting control circuits.
