ET3KRS 30AH Lithium Battery UPS Application Case for Monitoring S

I. Project Overview

This project serves Wuhan Weimou Co., Ltd., focusing on the stable power supply demands of on-site monitoring systems. Monitoring equipment requires long-term continuous operation, and is extremely sensitive to mains power fluctuation, instantaneous power failure and voltage surge. Short power outages will easily cause monitoring screen blackout, video recording interruption, camera offline, and monitoring data loss. To solve the above problems, the project adopts ET3KRS UPS host equipped with a 48V 30AH lithium iron phosphate battery pack. The system provides 24-hour uninterruptible emergency power guarantee for surveillance cameras, monitoring hosts, data storage devices and network transmission equipment, ensuring the monitoring system runs continuously, stably and reliably without dead time.

II. Core Equipment Configuration

According to the 24/7 continuous operation characteristics and low failure rate requirements of the monitoring system, the project adopts a high-stability lithium battery UPS power supply solution with compact layout and intelligent protection:

1. Power Supply Host: The ET3KRS high-frequency online UPS host outputs standard pure sine wave power, with high precision voltage stabilization and ultra-fast switching response. It can effectively filter grid voltage fluctuation and power clutter, avoid monitoring equipment restarting and screen jitter caused by unstable power supply, and ensure the real-time and consistency of video monitoring and data recording.

2. Energy Storage Battery: Equipped with a 48V 30AH lithium iron phosphate battery pack, it features high safety, low attenuation and long cycle life. Compared with traditional lead-acid batteries, it has smaller volume, lighter weight and better low-temperature performance. Built-in intelligent BMS battery management system realizes full protection of overcharge, overdischarge, overcurrent, short circuit and overheating, which can adapt to long-term floating charge and standby operation of monitoring equipment, and provide stable emergency power supply during power failure.

III. Application Advantages of the Solution

1. Zero-Interrupt Monitoring Operation: The ET3KRS UPS host realizes seamless switching between mains power and battery power. In case of sudden power failure, it can instantly take over power supply, effectively preventing monitoring offline, video missing and equipment shutdown, ensuring no blind spot in whole-process monitoring and complete and intact monitoring data.

2. Stable and Anti-Interference Power Supply: The system has excellent grid adaptability and anti-electromagnetic interference ability. It can operate stably in complex power environment, effectively avoid picture distortion, screen flicker and signal delay of monitoring equipment caused by power problems, and improve the clarity and stability of monitoring images.

3. Compact and Easy for Centralized Deployment: The whole set of equipment adopts integrated and compact design, which saves installation space and is convenient for centralized installation and management in monitoring machine room and on-site cabinet. It is highly compatible with various standard monitoring equipment and storage systems, with strong universality for security monitoring scenarios.

4. Low Maintenance and Long Service Life: The 30AH lithium iron phosphate battery pack supports long-term floating charge operation required by monitoring systems, with low daily attenuation and long service life. It greatly reduces the frequency of manual maintenance and battery replacement, reduces the later operation cost of the monitoring system, and improves the overall stability of the security system.
