ET3KRS + 1PCS LD48V50AH Lithium Battery UPS Application Case for

I. Project Overview

This project serves a technology enterprise in Zhengzhou. The company’s on-site office equipment, terminal systems, small and medium-sized monitoring and intelligent equipment are easily affected by municipal mains power fluctuation, instantaneous power failure and voltage surge in daily operation. Minor power abnormalities may cause equipment restarting, system offline, data caching failure and abnormal operation of terminal equipment, affecting the normal progress of daily office and on-site operation. To solve the hidden dangers of unstable power supply and unguaranteed emergency power failure, the customer adopts ET3KRS UPS host matched with 1 set of LD48V50AH lithium iron phosphate battery pack. The system provides stable voltage regulation and reliable short-term emergency uninterruptible power supply for the company’s daily office equipment, on-site intelligent terminals and supporting systems, ensuring stable and continuous operation of daily business and on-site equipment.

II. Core Equipment Configuration

Combined with the conventional power load demand, indoor and on-site installation environment and daily standby power demand of the enterprise, the project adopts a compact, efficient and high-safety standard lithium battery UPS power supply configuration:

Power Supply Host: The ET3KRS high-frequency online UPS host has stable performance and high voltage stabilization accuracy. It outputs standard pure sine wave power, which can effectively filter grid clutter and suppress voltage fluctuation. It realizes zero-delay seamless switching during power failure, effectively avoiding equipment operation failure and system abnormality caused by power quality problems and instantaneous power failure, and stably protecting daily office and intelligent terminal equipment.
Energy Storage Configuration: Equipped with 1 set of LD48V50AH lithium iron phosphate battery pack, the battery has high safety, low attenuation and stable discharge performance, fully meeting the enterprise’s daily standby and short-time emergency power supply demand after mains power failure. The built-in intelligent BMS battery management system realizes full protection of overcharge, overdischarge, overcurrent, short circuit and overheating. It adapts to long-term floating charge standby of conventional office and on-site equipment, ensuring safe and stable energy storage and power output.

III. Application Advantages of the Solution

Stable Power Supply to Ensure Daily Operation Continuity: The ET3KRS UPS host achieves seamless switching between mains power and battery power. It can instantly take over power supply in case of sudden power failure or voltage instability, preventing equipment shutdown and system offline, and ensuring the continuous and stable operation of enterprise daily office and on-site supporting equipment.
Compact and Efficient, Easy to Deploy: The whole set of equipment adopts a standardized and compact design, with small floor space and convenient installation and wiring. It is suitable for indoor machine room and on-site cabinet installation, perfectly matching the conventional power consumption scenarios of enterprise office and small and medium-sized intelligent equipment, with high overall compatibility and practicability.
High Safety and Low Attenuation: The LD48V50AH lithium iron phosphate battery pack has excellent thermal stability and safety, with no hidden dangers of combustion and explosion in daily operation. It features low daily attenuation and long cycle life, adapting to long-term standby operation of enterprise equipment, effectively reducing daily maintenance frequency and later operation costs.
Excellent Power Purification Ability: The system can effectively purify municipal power grid interference, solve common power problems such as voltage fluctuation and power surge in office and factory areas, provide high-quality pure sine wave power for precision terminal equipment, and avoid equipment aging and data errors caused by poor power quality.
