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 surge of current upon startup, caused by the large number of switching power supplies. For displays with power exceeding 10KW, a specialized intelligent power distribution cabinet for LED displays should be provided.
This product features an indoor shell, with a total load power of 90KW, capable of connecting 27 single-phase electrical equipment lines (such as display circuit, air conditioning circuit, and fan circuit). It offers overcurrent and short-circuit protection, with step-by-step, graded power-on delay. It can be manually controlled for power on/off, and equipped with a multi-functional card for remote automatic power-on and power-off functions. The standard circuit breaker is a Delixi product, while the contactor is a Schneider product. The multi-functional card power supply utilizes Mingwei's high-reliability industrial-grade products to ensure stable system power supply.
Feature Highlights
1.All models feature two-level protection; the input circuit breaker is a plastic-case circuit breaker, and the output circuit breaker is a miniature circuit breaker. 2. Supports multi-functional cards for remote intelligent control of the power system.
3.Choose between manual or multi-functional card control for up and power-off operations.
4.Standard with overcurrent and short-circuit protection.
5.Phase voltage indicator lights with different colors to distinguish the phase power supply status.
6.Manual, stop, and automatic, three-position panel control switch.
7.Multi-channel step-by-step sequential power-on delay.
8.All key components are made with internationally renowned brand components; cables are all selected from national standard copper cables, with all cables utilizing purple copper terminals for termination, and the wire diameters inside the box are all equipped with over 20% safety margin.
9. Products are designed and manufactured in accordance with national standards, featuring unique reinforcement in the shell design and made of sheet metal with a thickness of 1.2mm or more, coated with paint.
10.All models come standard with inspection outlets equipped with leakage protection and lighting control circuits.
