Technical advantage two, green environmental protection, high efficiency and energy saving


1Green environmental protection, reduce procurement costs


The EA660 series uses IGBT average current control technology, the load changes from 10%-100%, the PF is greater than 0.99, THDI less than 3%, no interference on the power grid, is truly green power.

The topology as shown below:


The traditional SCR6 pulse rectifier IGBT rectifier waveform waveform of traditional SCR12 pulse rectifier waveform

The input harmonic current, harmonic current of 3% input: < > > 10%: 30% input harmonic current

The input power factor: 0.99 input power factor: 0.85 input power factor: 0.90


The input power due to the use of higher cost, the smaller the input harmonic current can greatly save users, mainly in the following aspects:

1, reduce the front end of the UPS power transformer and generator capacity ratio, improve the utilization rate of power generation and transmission equipment;

2, reduce the input ratio of the cable specifications and switching capacity;

3, reduce the power loss and power transmission equipment;

4, reduce the harmonic current caused by electrical equipment malfunction.

For example:

Calculated in accordance with the configuration of UPS capacity 100KVA:

EAST EA66100 (100KVA) the ratio of generator capacity is 1.2:1, 1.2 * 100KVA=120KVA

Domestic generators ratio capacity of some brand 100KVA 3:1, 3 * 100KVA=300KVA

Therefore, EAST products only need 120KVA generator at home and abroad, some brands need to configure a 300KVA generator, thus increasing the cost of the user 180KVA generator.



2High efficiency and energy saving, reduce operating costs


EA660 series UPS uses three level vector modulation technology, reduces the switching losses within the device, so as to enhance the efficiency of the whole machine, the work efficiency is more than 93%.

The efficiency is high, the user cost is lower; on the contrary, the lower the efficiency, will increase operating costs;


For example:

EAST EA660 series machine efficiency is 93%, some domestic and foreign brand power machine efficiency is 88% (loss, SCR rectifier input loss, harmonic filter control method reduces the overall efficiency)

Taking 100KVA UPS as an example, according to each UPS runs 24 hours a day, electricity 1.5 yuan / kWh calculation, the efficiency was 88% UPS per year to pay electricity: 0.05*100000*0.8*24*365*1.5=5.2 million;

Therefore, if the use of our EA660 series UPS, every year can save 52 thousand yuan electricity;


Technical advantage three, flexible configuration, on-demand expansion, dynamic growth;

EA660 UPS for the whole series of modular design, the system capacity can be extended from 20KVA to 250KVA, the design concept of power module is running in the system can easily be removed and installed, without affecting the operation and output of the system;

If the user in accordance with the pre modular UPS maximum system capacity configuration of switch and cable, when the load increase later, only need to buy the power module, the UPS can be expanded to the power required, completely avoid the traditional UPS for the first time, the shortcomings of the large equipment investment, make the investment plan to achieve "on-demand expansion". Let the user with business development to achieve "dynamic growth", not only meet the demand expanded equipment, but also reduce the initial purchase cost.

In general, the user is expected in UPS capacity, often appear to underestimate or high expected conditions, EA660 Series modular UPS can effectively solve the above problem, construction and investment stages to help users in the future development direction is not clear case. When the user load increases, only need to increase the planning stage of the power module.


For example:

A room, the load is 60KVA, 1 years after the load capacity of up to 80KVA; 2 years after the load capacity of up to 120KVA; 3 years after the load capacity of up to 160KVA, the subsequent increase in load capacity.

The traditional UPS has two kinds of configuration:

1, according to the customer's actual load configuration UPS, the results are as follows: 60KVA1; 20KVA1; 40KVA1; 40KVA1 Taiwan, a total of 4 sets of UPS configuration, and each configuration of the UPS need UPS placement, and the configuration and installation of input and output cable, the UPS and the installation cost is much higher than buy a the cost of 160KVA.

2, according to the following maximum load capacity configuration UPS, therefore, need to configure a 160KVA UPS, but due to the current load power is 60KVA, the load rate is 37%, the efficiency was 78%, with 88% full load efficiency is 10%,A year of electricity costs increased by about 63 thousandIn addition, UPS will also cost a year of sluggish 100KVA.



Modular configuration design of UPS:

According to the following maximum load capacity, the configuration of a 160KVA system cabinet, 4 20KVA power module (1 redundant backup) 60KVA+1 configuration cost, improve the efficiency and save the cost of procurement early, with the subsequent load power increases, the direct purchase of power module, without increasing the area and installation;


Technical advantage four, easy maintenance and intelligent management design

1MTTR(The mean time to repair)Close to0


The traditional UPS system are taken to bypass work in daily maintenance, equipment maintenance period, so the load not protected by UPS, at this time if the AC power interruption and overload fault, will cause the load power supply interruption or equipment damage. At the same time, equipment maintenance also need to go through a series of cumbersome procedures: the system administrator to notify the manufacturer - manufacturers rushed to the site maintenance: maintenance outage. The traditional UPS maintenance time in more than 2 hours, or even more than 1 days.

In order to solve the traditional UPS which exists in the maintenance problems, EA660 UPS uses a series of advanced technology of hot swap module,Charging module and system monitoring module, power moduleHot plug can be online, without power cut operation. The online parallel system maintenance, at the same time the operation without special instruments and techniques can be carried out, the general maintenance time will be able to solve the problem in 1 minutes.

EA660 series UPS through the hot swap technology makes the single power module can be any online input or exit, to overcome the traditional UPS to bypass maintenance technical problems, make the maintenance convenient at the same time achieve the UPS abnormal, free expansion and redundant two performance, fully meet the actual needs of users.


2In English, large screen display, can display the parameters of input and output, batteries, rectifier, bypass, and the work of the whole state, historical records, battery management and other functions, to facilitate maintenance personnel maintenance operation;


3Intelligent monitoring and management

The monitoring module, USB, RS485, RS232 and other dry contact communication interface monitoring the operation state of UPS. With remote SNMP network management (optional) function, support TCP/IP protocol to realize remote network management. UPS SMS alarm management platform, send text messages to mobile phone through GSM network can alarm the administrator. Support networking scheme is flexible, convenient everywhere, monitoring and management of UPS.
