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 upon startup. Since LED displays are powered by numerous switch-mode power supplies, they can easily create a shock to the power grid. Therefore, for displays with power exceeding 10KW, a dedicated intelligent power distribution cabinet for LED displays should be installed.
This product features an indoor housing with a total load power of 70KW, capable of connecting 21 single-phase electrical equipment lines (such as display circuit, air conditioner circuit, fan circuit); it provides overcurrent and short-circuit protection with step-by-step delayed power-on. It supports manual power on/off, remote automatic power-on/off via a multi-functional card, and power-off functionality. 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 card 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 status.
6.Manual, Stop, Automatic – Three-position panel control toggle switch.
