Let ups "Impressionist users" re understand reliability

In the last decade or so , Push UPS The rapid development of high frequency machines , Is the sudden rise of Dr. Rupeng 、 Century interconnection 、 Wanguo data and other data center hosting service providers . Because of the huge cost pressure , These even preceded the telecom operators to accept the low cost 、 High frequency machine with small space .

2010 Years later , In those data centers that have sprung up rapidly , The configuration of dozens of high-frequency machines is not uncommon , The industry is also surprised .

After the demand wave broke out , What is even more surprising is the consequent reliability problem .“ Some large data centers have problems with high-frequency machines , Soon the whole Internet will know .” Weidi Technology （Vertiv） Greater China ACP Li Xu, general manager of the product department, still has a fresh memory of the market situation at that time , “ High frequency machines are technically difficult , But at the beginning, the market was too concerned about efficiency 、 cost 、 Improvement in land occupation , Wait until problems occur frequently , Only then triggered the market to UPS Re recognition of reliability problems .”

From the perspective of market competition , This is for technology leading TOP level UPS It is a self-evident opportunity for manufacturers . The technical accumulation on the high-frequency machine makes Weidi Technology （Vertiv） stay 2015 Around the year （ At that time, the company was called Emerson Network energy ） Start calling on customers to focus on reliability issues —— at that time , Weidi Technology （Vertiv） Will return to “ reliability ” As UPS The core value of products and solutions , And start to build a competitive barrier on product technology and concept .

This early decision-making gives the dimension technology （Vertiv） In the market, a distinct “ label ”—— Now ,“ Uncompromising reliability ” This slogan has been deeply rooted in the hearts of the people .

“ Uncompromising reliability expresses our adherence to reliability ,” Li Xu said ,“ But this kind of persistence is not to stick to the power frequency machine , It is aimed at the interests of customers .”

It's not just the hosting service provider in the data center , With the wide acceptance of high-frequency machines in the market , Both reliability and energy efficiency are important for UPS It has become a must for manufacturers .

Weidi Technology （Vertiv） The strategy of , First, based on industry insight and technology accumulation , Unify the evolution direction of the product with the customer value , The pursuit of uncompromising reliability of high-frequency machines is an example ; Second, combine the above product concepts with the customer's business . The latter seems to Li Xu , It's dimension technology （Vertiv） Put forward “ uncompromising ” Then another wise decision .

After the wide application of high-frequency machines , There is a relative “ Impressionism ” Way of thinking . They ask themselves , What is the high-frequency tower machine you want , Still want high-frequency modular products ？

This kind of self questioning shows some users' cognition of the product ： On one side are more reliable products , On the other side is more convenient maintenance and expansion .

From the perspective of product development history , There is no difference in this understanding . There are few high-frequency machines in parallel because of the internal units , Few components , Simple control , The safety is inherently high ; This is consistent with the flexibility and easy maintenance of modular products , Is their inborn attribute .

“ Behind the user cognition, it represents the different business demands of the user .” Li Xu thinks , This demand has affected the manufacturers' different setting of product roadmap .

Weidi Technology （Vertiv） Hope to break the boundary of this product , Because uncompromising reliability should have served the business itself .

“ Optimum particle size ” The concept of "is put forward" , Weidi Technology （Vertiv） take 400kVA Large module of “ implant ” The body of the high-frequency all-in-one machine product .

The corresponding product is Vertiv LiebertEXL S1. Its rectifier and inverter adopt three-level technology , The efficiency of dual conversion mode is as high as 97%, And the efficiency under light load can be improved through intelligent parallel connection ; And in the newly launched dynamic online mode , The equipment can provide up to 99% Operating efficiency .

The key to the product lies in the combination of modularity and reliability “ Traditional contradictions ” The solution of the .

400kVA The design of the module itself corresponds to the integration UPS The reliability of the , At the same time, on the demand of convenient capacity expansion , It also does not need to use the maintenance bypass like the tower crane .

But for O & M personnel ,400kVA The module of is obviously not convenient for operation and maintenance , No one can hot plug such a large module . Weidi Technology （Vertiv） Single phase module design is introduced here , In short , It decomposes a three-phase integration into three single-phase integration modules ; At the same time, all the internal control circuits are standardized and modularized .

This innovative design completely eliminates the contradiction between modularity and reliability .“ We did not reduce the reliability of the system , At the same time, it improves maintainability and scalability .” Li Xu said ,“ For users of the same size ,400kVA The integrated module finally realizes the optimal particle size .”

in fact , stay Vertiv LiebertEXL Before the launch of 2014 year , Weidi Technology （Vertiv） It has been popularized for megawatt large data center users 400kVA Our modular products , And applied it to Vertiv LiebertTrinergy Cube This megawatt intelligent control type UPS In the power supply system . Its previous generation of products used 200kVA Modular design , Widely praised .

“ The greater the power of the integrated module , The higher the technical requirements .” Li Xu revealed that , Weidi Technology （Vertiv） At the maximum, it can be a single module 600kVA The level of ,“ The integrated high-power module technology will replace the traditional tower and modularization UPS, Become MW level UPS Trends in power supply systems , Because it maximizes customer value .”

This acceptance will depend on the user's consideration based on cost —— from 5G And other trend businesses , The industry's prediction of the proportion of global data center energy consumption in global energy consumption has changed dramatically .

In earlier institutional forecasts ,2025 Year to 2030 The proportion of data center energy consumption in is generally about 10%～15%; Now, , The latest forecast has pushed this ratio close to 20% The level of .

This background changes , Obviously, it will greatly increase the attention of data center owners to energy consumption —— The improvement of power efficiency in any link , Will affect the cost expenditure to a greater extent .

Tradition , The focus of energy conservation has always been “ Big energy consumer ”—— Refrigeration , But with the improvement of refrigeration energy-saving technology , The energy consumption proportion of power supply and distribution also began to increase . Now? , The industry has generally realized that , The energy-saving level of the latter is affecting the cost of users to a greater extent .

In this context , Reduce UPS Loss of , And improving manageability have also become important consideration objects in the cost dimension .

A configuration 400kVA UPS Users of , The corresponding annual electricity charge is about 20 Ten thousand yuan or so , This is related to UPS The purchase cost of is quite . If UPS The power loss is reduced 1 percentage , Electricity bills can be reduced by about 20%, This corresponds to about 4 Ten thousand yuan of electricity savings .

So the user UPS It is not surprising that energy consumption has become increasingly sensitive , Because they directly generate value .

and “ Optimum particle size ” Match , Weidi Technology （Vertiv） Another idea put forward is “ Reliable full working condition ”—— In bypass mode , The power supply efficiency of the bypass is improved to 99%, Harmonic is from 20% Down to 3%—— Ensure high reliability in bypass power saving mode .

99% The efficiency of UPS In terms of products , Basically, it means no power consumption , The electricity cost savings it brings far exceed those due to bypass “ upgrade ” Resulting in increased costs .

In this way , Weidi Technology （Vertiv） The uncompromising reliability followed has penetrated into the product solution from two dimensions ：“ Optimum particle size ” Let reliability and maintainability exist at the same time ,“ Reliable full working condition ” Makes reliability affordable .

So far , In the past few years , Weidi Technology （Vertiv） These leadership gains in the cloud market , It has influenced the exploration of edge computing .

Although the edge computing market has not yet exploded , But at least three market characteristics have emerged ： This is a huge market , This is a rapidly growing market , This is also a market with diversified demand —— It involves almost every industry segment of the traditional market , From industry 、 Medical care , To education, etc .

“ The market needs to be modular 、 Highly integrated solutions .” Li Xu said , Weidi Technology （Vertiv） Leadership and experience in the cloud are helping them to take the lead in edge computing . He thinks that ,UPS The trend characteristics of products and overall solutions in the cloud , It will also be shown in the edge calculation , This includes the modularization of the whole power supply and distribution system 、 Prefabrication and intellectualization .

He revealed that , Weidi technology in the second half of this year （Vertiv） We will continue to introduce new products for edge scenes .
