Modular UPS power supply and distribution system module of d
(1)
Introduction to modular UPS of data center:
Industrial modular UPS power supply follows and conforms to the characteristics of energy saving, green and environmental protection applications, greatly improves the availability and reliability of equipment, and reduces the investment, operation and maintenance costs of equipment.
UPS features of modular data center:
(2) precision distribution cabinet
Power input unit:
Divided into single electric input and double electrical input, input side is equipped with power indicator, 8 inch touch screen control and display parameters, such as detection of electricity information, effective management of power distribution system can detect the three-phase power supply into line 2 road electric parameter information, provide the main into line voltage, current, power, and power, power factor, harmonic content, and branch circuit of voltage, current, power, switch state, such as complete information, and can realize the branch voltage and current trend diagram, etc., the data center, the communication board (stand) under effective control, greatly improve the power supply system security.
Equipped with RS232/RS485, Ethernet interface, communication interface, can monitor all parameters of the display screen remotely, flexible query.
Advanced alarm function:
Two-level threshold alarm can be set, and provide effective risk early warning, on the main road overvoltage, undervoltage, overload, three-phase imbalance, input frequency overrun, transformer temperature, lightning protection device failure, such as the limit, the branch circuit circuit switch trip and alarm set, and can alarm set appropriate time delay, and avoid the peak load input zero alarm.Alarm record includes "real-time advance" record and "historical alarm" record, which is convenient for users to analyze the cause of failure and its prevention.And can carry on the centralized monitoring through the communication interface.Dual power input is equipped with a power controller, which can effectively and intuitively select the common power supply and standby power supply. In case of failure of the common power supply, it will be immediately switched to the standby power supply and automatically converted when the common power supply is restored.
Lightning surge protection unit:
It can effectively protect against surge and overvoltage, usually reduce the loss caused by natural lightning strike, and directly protect communication network equipment, computer system and precision equipment.
UPS power supply:
Rack UPS power supply, with 19 inch cabinet, ordinary UPS USES ordinary power screen, compact structure design, beautiful.
Bypass unit:
UPS maintenance problem can be solved. In the case of UPS failure, the core load can be continuously powered by closing bypass switch selectively, which facilitates UPS maintenance.In addition, the indicator light can display the status of each switch, indicating clearly, simple operation, easy to operate safely.Switch lock, prevent non-professional operation.
Mains power distribution unit:
Each road is equipped with indicator lights, so that the on-off state can be directly seen. The connection method adopts the average distribution of each item to effectively solve the phase imbalance.
Battery pack:
For small machines, short time standby, the battery can be integrated together, so as to save the traditional battery cabinet, and save space
(3) sealed lead-acid battery
Data center sealed lead-acid battery features:
Is a maintenance free:
Adopt the unique gas recombination technology, do not need to regularly refill liquid maintenance, reduce the worry of users.
High safety and reliability:
Automatic safety valve can prevent gas from being sucked into the battery to affect its performance, but also to prevent the gas generated by charging and other abnormal internal pressure damage to the battery.Fully sealed battery under normal floating charge will not have electrolyte and acid mist discharge.At the same time, the use of independent patented technology of battery tray and battery supporting use, to ensure the use of battery more safe.
Long service life:
S in 20 ℃ environment, small sealed battery floating life up to 3 ~ 5 years, fixed type sealed battery floating life is 8 ~ 10 years.
Low self-discharge rate:
S using special lead calcium alloy, the separator, the electrolyte, and strictly control each production working procedure of impurities, under the environment of 20 ℃, the SHIP battery don't have to be added in 6 months can be normal use of electric power.
Highly conductive
Adopt copper core silver-plated terminal and special design to ensure excellent electrical performance.
Strong adaptability to the environment:
S in 20 ℃ + 50 ℃ ambient temperature, suitable for desert, Gao Yuanxing climate.It can be used for special power supply in riot area.
Strong directivity:
Special diaphragm (AGM) firmly adsorbs the electrolyte so that it does not flow.No matter the battery is placed vertically or horizontally, it will not leak, ensuring the normal use.
Green pollution-free:
B quiet, and no pollutants discharge.Battery room does not need to use acid-proof anticorrosion measures, and electronic instruments and other equipment with a room.
(iv) intelligent PDU
Characteristics of intelligent PDU of data center:
B ordinary PDU, the total input current 10A/16A/32A is optional, the output current 10A, 16A is optional, the socket for the national standard socket, universal socket, IEC socket multiple socket options.
Smart PDU, total input current 10A/16A/32A is optional, output current 10A, 16A is optional, the socket is the national standard socket, IEC socket multiple socket options, with automatic alarm function and permission management.
B according to customer needs can be optional hot plug, anti-shedding, lightning protection and other application functions, installation support: horizontal installation or vertical installation.
