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. Since LED displays are powered by a large number of switching power supplies, they can easily cause a shock to the power grid. Therefore, for displays with power over 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 40KW, capable of connecting 12 single-phase electrical equipment (such as display circuit, air conditioning circuit, fan circuit); it can achieve overcurrent and short-circuit protection with step-by-step and graded power-on delay. It allows manual power-on and power-off, remote automatic power-on and power-off via a multifunctional card, and features a standard circuit breaker from Delixi and a contactor from Schneider. The multifunctional 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 functions.
4.Standard with overcurrent and short-circuit protection.
5.The sequence of different colored power indicator lights distinguishes the phase wiring power status.
6.Manual, Stop, Auto — three-position panel control toggle.
7.Multi-channel step-by-step sequential power-on delay.
8.All key components are made with internationally renowned brand components; all cables are selected with national standard copper cables, and all cables use purple copper terminals for crimping, with each cable having a 20% or more safety margin in the box.
9. Products are designed and manufactured in accordance with national standards, featuring unique reinforcement in the housing design and made of sheet metal with electrostatic powder coating of 1.2mm thickness or more.
10.All models come standard with circuit breakers for safety and lighting control circuits.
