Description
Technical field
The utility model relates to a kind of uninterrupted power supply, specifically is that a kind of network equipment is used uninterrupted power supply.
Background technology
Along with computer technology, the develop rapidly of information technology and related industry, computer and Related product are widely used in all trades and professions, increasing significant data, image and literal will be by Computer Processing and storages.If have a power failure suddenly at work, the data and the program of the random asccess memory in the computer will lose or damage.Even more serious is if the read-write head of this computer-chronograph is worked, very easily to cause the damage of magnetic head or disk.If these data are the data in bank clearing system or the political affairs family dependant transaction system, consequence is with hardly imaginable.Simultaneously, some the hard pulse spikes in the electrical network, interference such as high energy surge also can cause the misoperation of computer and cause unnecessary loss.For fear of these situation occurring, must a kind of power-supply system of design, it can be after power failure recovers the power supply to load in time of 10ms, and Here it is occurs and widely used ups power system in recent years.Present UPS has been widely applied to the every field of national economy, as: scientific research, national defence, space flight, communication, health care, industrial and agricultural production, the political affairs family dependant of bank, commerce and trade are sold, communications and transportation or the like.
The online uninterrupted UPS of ON-LINE; Traditional online uninterrupted power supply technical scheme mainly is to utility grid: when civil power just often; The alternating voltage of input constantly charges to battery through charging circuit; The AC/DC circuit converts alternating current into direct current simultaneously, is the alternating current supply load with dc inverter again through inverter then.And when city's electrical anomaly; Storage battery is started working; This moment, the direct current in the battery was transformed into AC sine wave electric energy supply load through inverter, therefore no matter civil power normally whether, inverter is in running order all the time; The voltage fluctuation of fundamentally having eliminated electrical network and the influence of disturbing load have really realized noiseless, voltage stabilizing and 0 change-over time to load.Traditional online uninterrupted power supply power ratio is big, volume is big, cost is high, so the general user only is directed against the UPS that uses under the personal computer environment, its loadtype is a desktop computer; Or other more powerful power consumption equipment, and what face is the sine wave alternating current of 220V, with being difficult to take into account low-power equipment under office or the home environment like router; Modulator-demodulator; The VOIP telephone system, telesecurity IP Camera, warning system etc.; The work of giving, life and work have brought inconvenience, have so expedited the emergence of the online direct current UPS of miniature long delay to above low-power equipment adapter.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of efficient height, volume is little, cost is low and the network equipment of applied range is used uninterrupted power supply.
To achieve these goals, the technical scheme of the utility model employing is:
The network equipment is used uninterrupted DC power supply; It is characterized in that: it is to be made up of adapter, rectifier, charger, rechargeable battery, selective booster circuit module and power change-over switch module; Through the alterating and direct current of 8-15V of adapter output, behind rectifier, the one tunnel directly exports to load; Another road is the rechargeable battery charging through charger, and rechargeable battery is an electric through selective booster circuit module, power change-over switch module; Be provided with manual output voltage selector switch in the said selective booster circuit module.
Said rechargeable battery is the battery of 6V/4AH.
Also be connected with battery low-voltage protection circuit module on the said rechargeable battery.
Be connected with alarm and under-voltage indicator light in the said low-voltage protection circuit module.
The selectable voltage of said selective booster circuit module output is 9V and 12V.
The beneficial effect of the utility model: owing to adopt above-mentioned structure, on the basis of traditional online uninterrupted power supply, making and simplifying, is to design to 12V and 9V dc power source adapter simultaneously, has efficient height, little, the low cost and other advantages of volume; Because the direct current of exportable 9/12V provides the emergency backup power supply for thousands of users, for example: router, modulator-demodulator, VOIP telephone system, remote control network video camera, warning system and other emergency set or the like; Power supply unit that simultaneously can compatible Ethernet; Also can be used as the charge independence device of mobile phone and other common apparatus.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the electric theory diagram of the utility model;
Fig. 2 is an electrical schematic diagram shown in Figure 1.
Among the figure: 1, adapter; 2, rectifier; 3, charger; 4, rechargeable battery; 5, selective booster circuit module; 6, power change-over switch module; 7, battery low-voltage protection circuit module; 8, alarm; 9, under-voltage indicator light; 10, manual output voltage selector switch.
Embodiment
Like Fig. 1, shown in 2; The network equipment is used uninterrupted DC power supply; It is to be made up of adapter 1, rectifier 2, charger 3, rechargeable battery 4, selective booster circuit module 5 and power change-over switch module 6; Through the alterating and direct current of 8-15V of adapter 1 output, the one tunnel directly exports to load behind rectifier 2; Another road behind rectifier 2 is rechargeable battery 4 chargings through charger 3, and rechargeable battery 4 is an electric through selective booster circuit module 5, power change-over switch module 6.Be provided with manual output voltage selector switch 10 in the said selective booster circuit module 5, through manual output voltage selector switch 10 optional 9V voltage output or the outputs of 12V voltage.
Said rechargeable battery 4 is the battery of 6V/4AH, also is connected with battery low-voltage protection circuit module 7 on the rechargeable battery 4, is connected with alarm 8 and under-voltage indicator light 9 in the low-voltage protection circuit module 7.
The parameter of the utility model is following:
