1. Industry Background: Why Do Critical Scenarios Urgently Need High-Reliability UPS? With the rapid development of digitalization and AI technology, critical scenarios such as government affairs systems, financial transaction platforms, medical equipment, and data centers have put forward unprecedented high requirements for the "continuity, stability, and intelligence" of power supply. According to industry statistics, a single power outage lasting more than 10 minutes may cause financial institutions to lose over one million yuan, lead to the risk of equipment shutdown in medical systems, and even result in data loss and business interruption in data centers. Traditional UPS has pain points such as "difficult expansion, long maintenance downtime, and low energy efficiency": the fixed-power design requires the overall replacement of equipment when business grows in the later stage; maintenance requires power outage; and the energy efficiency loss during long-term operation can reach more than 10%. Against this background, modular UPS has become the core choice to solve the power supply problems in critical scenarios due to its advantages of "flexible expansion, hot-swap maintenance, and high energy efficiency" — and the SY-M series modular UPS of Hefei Shuyi Digital Power is a representative product in this field. 2.

SY-M Series Modular UPS: Core Advantages and Full-Scenario Adaptation Shuyi Technology's SY-M series modular UPS covers the full power range of 20kVA-1600kVA, adopts the "three-in three-out, dual-conversion online operation" mode, and can provide flexible product choices according to the power requirements and installation environments of different scenarios. Its core advantages can be summarized into four dimensions: "reliability, flexibility, intelligence, and efficiency". (1) High Reliability: Ensuring Zero Power Outage Risk in Critical Scenarios N+X Redundant Design: It supports parallel operation of multiple modules. Even if a single module fails, the remaining modules can automatically take over the load to avoid power supply interruption, which is especially suitable for "zero-tolerance" scenarios such as finance and medical care. Core Component Upgrade: It adopts integrated packaged IGBT modules, which have fast switching speed, low loss, and strong impact resistance, and can cope with grid voltage fluctuations and load mutations. Wide Input Voltage Range: The input voltage supports 304~485VAC (full load). Even if the grid voltage fluctuates greatly (such as in remote areas or industrial scenarios), it can still output stably, reducing frequent charging and discharging of the battery and prolonging the battery life. Battery Cold Start Function: In emergency situations without commercial power, the UPS can be started directly through the battery to quickly restore power supply, which is suitable for emergency scenarios of sudden power outages. (2) Flexibility: On-Demand Expansion to Adapt to Different Installation Environments Full Power Range Coverage: From 20kVA small computer rooms to 1600kVA large data centers, the SY-M series can meet the power requirements of different scenarios and avoid resource waste caused by "using a large device for a small load". Modular Hot-Swap: The power modules and static bypass monitoring modules support hot-swap. Maintenance does not require shutdown, and the replacement time of a single module is only 5 minutes, which greatly reduces the risk of business interruption. Multiple Installation Methods: It provides multiple installation methods such as rack-mounted (compatible with 19-inch standard cabinets), tower-type, and container-type, adapting to different site conditions such as data centers, base stations, and industrial workshops. Flexible Parallel Expansion: It supports direct parallel operation of multiple UPSs. When the business grows in the later stage, the power can be increased only by adding modules without replacing the overall equipment, reducing the expansion cost. (3) Intelligence: Remote Management and Precise Operation and Maintenance Large-Screen Touch Interaction: Equipped with a 5.7-inch/10.4-inch color LCD touch screen, it supports more than 10 languages including Chinese, English, Russian, and French. It can display real-time data such as load rate, battery status, and fault information, with intuitive and convenient operation. Powerful Remote Management: It is equipped with RS232 and RS485 interfaces as standard, and an SNMP network communication card is optional. It supports remote monitoring, parameter setting, and fault alarm (such as SMS alarm and email alarm), so that operation and maintenance personnel can grasp the equipment status without being on-site. Intelligent Battery Management: It adopts the "three-stage charging" technology to avoid over-charging and over-discharging of the battery, prolonging the battery life (the life of lead-acid batteries can be extended by more than 20%). At the same time, it supports battery status self-test and fault early warning. System Self-Diagnosis: It has built-in fault recording and historical data storage functions, which can automatically identify problems such as module faults and power grid abnormalities, and generate diagnosis reports, reducing the difficulty of operation and maintenance. (4) High Efficiency: Green and Energy-Saving to Reduce Long-Term Operating Costs Ultra-High Operating Efficiency: The efficiency is ≥95% in normal mode and up to 99% in economic mode. Compared with traditional UPS, it can reduce a large amount of power loss every year, which is especially suitable for scenarios such as data centers that "operate 24 hours a day". Intelligent Sleep Mode: It automatically adjusts the number of operating modules according to the load rate. When the load is low, some modules sleep to reduce useless power consumption. For example, when the load rate is less than 40%, 50% of the modules can be turned off, and the energy efficiency is increased by 10%-15%. Low Harmonic Pollution: The input power factor is >0.99, and the input harmonic current THDi is <3%, which avoids interference to the power grid, meets the environmental protection requirements of green data centers, and reduces electromagnetic interference to other equipment. (5) Full-Scenario Adaptation: Covering More Than 10 Key Industries With its high adaptability, the SY-M series modular UPS has been widely used in: Government and Finance: Government affairs systems, bank transaction platforms, and securities servers to ensure data security and business continuity. Medical Industry: ICU equipment, nuclear magnetic resonance, and testing instruments to avoid medical accidents caused by power outages. Communication and Transportation: Base stations, rail transit signal systems, and airport dispatching centers to cope with high loads and frequent voltage fluctuations. Industry and Energy: Industrial automation equipment, photovoltaic energy storage systems, and power dispatching centers to adapt to harsh industrial environments. Education and Radio and Television: University data centers and TV station broadcasting systems to support long-term stable operation. 4.
