Data communication and core switching rooms undertake network data transmission services, and uninterrupted power supply is the key to stable network operation. As the core energy storage unit of room UPS systems, lead-acid batteries provide instant power supply during mains failures to ensure switches, routers and optical transmission equipment work continuously. They deliver stable voltage output and resist transient grid impacts to protect precision communication components. The sealed structure avoids electrolyte leakage, suitable for closed computer rooms. With simple maintenance and stable service life, they meet the 7×24-hour uninterrupted communication guarantee needs of government, enterprise and operator core rooms.
