Smooth capacity expansion
To avoid power interruption risk in capacity expansion, the capacity of UPS system is planned large enough to meet the power demand in 3-5 years, which leads to low efficiency operation at the initial stage due to low load rate
UPS5000-E uses module design and all of power module, bypass module, and control module support hot-swap, which makes smooth capacity expansion according to demand possible and reduces the initial investment
Availability is used to weight the degree that a system, subsystem or equipment is inoperable and committable state. It's positively related to MTBF (Mean Time Between Failures) and negatively related to MTTR (Mean Time To Repair)
For traditional UPS, customers need to seek help from the suppliers and a long recovery time is required because maintenance engineers need to shutdown and dismantle the UPS, and replace the failure components or boards.
Hot-swap design makes the failure recovery time reduce greatly, and the system availability can be effectively improved as a result. The engineers after trained can replace the failure module of UPS5000-E themselves in few minutes.
Online maintenance, reducing repair time greatly

High efficiency at low load rate
Due to redundancy configuration to ensure reliability and excessive configuration at the initial stage to meet the power demand in 3-5 years, the UPS system of traditional data centre often operates at load rate of 10% - 40% and the operating efficiency is far below the value claimed. It's estimated that the UPS loss takes up 6%-10% of the total power consumption in the data centre.
Huawei UPS can keep high efficiency operation at low load rate: 96% at 40% rated load and 95% at 20% rated load.
Given 200 kW load and air conditioner with a COP of 3:1
- 80, 183 kWh can be saved compared to traditional UPS (92% efficiency)
- 257, 731 kWh can be saved compared to legacy UPS (86% efficiency)
Intelligent hibernation design
When the load rate is very low (below 10%-15%), intelligent hibernation can be enabled and some power modules will switch to "standby" state to boost load rate and improve operating efficiency
To ensure reliability, at least one power module serves as redundancy module and when load increases dramatically, the sleep module will be awaked instantly
Achieving 99% efficiency at ECO mode
In good grid area, ECO mode can be enabled to improve efficiency to more than 99% and the maximal energy-saving can be achieved
At ECO mode, the load is powered by static bypass (the allowable input range can be set) and the inverter is in "standby" state
When input abnormality occurs, UPS5000-E will transfer to online mode in several milliseconds to ensure power continuity and quality
Small footprint and easy construction
High power density of up to 320kVA per cabinet, 50% footprint saving
Front accessible maintenance
Top/bottom cable entry compatible
Intelligent battery management, extending battery lifespan
Automatic switch between float charging and average charging and temperature compensation
Battery hibernation design to avoid long-term float charging, which improves battery service time greatly
Battery failure pre-alarm when its health grade is too low
Flexible battery configuration: 30-40 batteries per string allow customers to get the faulty battery out instead of replacing it
Low investment on power distribution system
THDi<3% & power factor>0.99 reduce the pollution to power grid and lower the expense on power distribution components including cables, breakers, etc.
Power walk-in technology boost the ratio of UPS capacity to D. G. capacity to 1:1.1 and cut the D. G. expense down
Redundancy design for energy control unit, communication buses to eliminate single point of failure
Fault-tolerant design for fan system: 30% load can be driven when 2 fans fail and 50% load when 1 fan fails
High grid adaptability
138-485 Vac wide input voltage range to minimise battery use: 485-305Vac for 100% load; 305-138 Vac for 100%- 40% load (derating linearly)
6 kV/5 kA lightning protection design, reducing lightning- related failure rate
High load adaptability
High output power factor of up to 1, 25% more load driven than traditional UPSs
The application of PFC technology in modern IT devices like servers, storages, routers improves the input power factor to more than 0.95. And if they are powered by UPS with output power factor of 0.7-0.8, the investment on UPS will increase remarkably
No derating for capacitive or inductive devices with a PF>0.5
High environment adaptability
No derating at 40°C to ensure power continuity
Conformal coating on PCB, improving adaptability to dusty or salty spray environment
NetEco 1000U Introduction
iManager NetEco 1000U can run on the Windows operating system and can be accessed through a web browser. The iManager NetEco 1000U enables you to monitor the key performance indicators (KPIs) and alarms of the UPSs in real time. In addition, it enables you to remotely control and manage the UPSs. This increases the centralized management and remote operation and maintenance capabilities for the UPSs. NetEco 1000U supports connection through USB Data lines, RS232 cable, or network cable.
