Jinan Jiahong Technology Co., Ltd
Jinan Jiahong Technology Co., Ltd
The system consists of a lithium-ion battery pack, a Battery Management System (BMS), a charging and inverter unit, an intrinsically safe power module, and a display and communication unit. It accepts a 127V underground power distribution input, which normally supplies power to equipment after voltage stabilization. Simultaneously, the power is converted into multiple intrinsically safe DC outputs at different voltages via an AC/DC intrinsically safe power supply module. In the event of a 127V power interruption, the system seamlessly switches to battery inverter output, ensuring continuous and stable power supply to downstream equipments and providing reliable power protection.
