The utility model discloses the adjustable server power supply of a kind of output voltage, comprise reference voltage operation circuit, also comprise a resistance regulation and control plate, the structure of described resistance regulation and control plate comprises a rheostat Rt, is parallel to reference voltage circuit.By technology of the present utility model, without dismounting or change power supply, only need shirtsleeve operation just can realize the regulation and control to output voltage, facilitate tester to use.Can export by knob regulation server supply voltage, while meeting server test by regulation output voltage four jiaos, the test needs such as draw partially, for server test, there is vital role.
Description
Technical field
The utility model relates to server power supply and field is established in server test, is specifically related to the adjustable server power supply of a kind of output voltage.
Technical background
Along with the develop rapidly of server industry, the effect in power supply server is more and more outstanding, and Server development test phase reasonably utilizes the performance index of power supply test server also more to come into one's own.At present a lot of server power supply developers all can test the stability of server components and parts when testing server, and wherein particularly the important point be exactly: when electric power output voltage fluctuates, can server normally be worked? in order to verify this point, need to revise the output voltage of power supply, after having revised, in order not affect other test uses, also need to change back again initial value, so repeatedly revise one come more loaded down with trivial details, two do not cause some damages to power supply unavoidably, affect the normal use of power supply.Under this background, design the adjustable server power supply of output voltage and just seem important, can solve the problem of above inconvenience.
Summary of the invention
The technical problems to be solved in the utility model is: consider, when server test, often can use the Voltage-output of the off-gauge 12V of power supply, 5V, 3.3V, and these outputs to be extremely important to the test of server performance.For convenient service device tester can select as required or adjust needed output voltage when testing, and increased the design proposal that regulates and controls voltage by changing resistance, by revolving rheostat, change resistance value, regulate and control reference voltage circuit, thereby reach the effect of regulation and control output voltage.
The technical scheme that the utility model adopts is:
The server power supply that output voltage is adjustable, comprises reference voltage operation circuit, also comprises a resistance regulation and control plate, and the structure of described resistance regulation and control plate comprises a rheostat Rt, is parallel to reference voltage circuit.
By the resistance regulation and control plate designing and the reference voltage operation circuit of corresponding output voltage connected (just designing inside when reference voltage circuit is Power Management Design), like this, adjusting resistance device knob position changes the size of rheostat access resistance, thereby change the resistance of reference voltage circuit, resistance has become, and output voltage also can change naturally.
Described resistance regulation and control plate also comprises a fixed value resistance R3, and Rt connects with rheostat.It is to regulate and control voltage in order to change resistance value that rheostat is set, and it is in order to prevent short circuit that fixed value resistance is set.
Described rheostat RT is knob rheostat.Be convenient to staff's regulating resistance size.
For 12V, 5V, the different voltage of 3.3V, corresponding resistance regulation and control plate is set respectively, and knob rheostat is separately set to respectively to outer casing of power supply.In order to facilitate the regulation and control of voltage, at outer casing of power supply place, with the knob rheostat of tag identifier regulation voltage, facilitate personnel to operate, and the corresponding knob of regulation and control 12V, 5V, 3.3V is identified.
The beneficial effects of the utility model are: without dismounting or change power supply, only need shirtsleeve operation just can realize the regulation and control to output voltage, facilitate tester to use.Can export by knob regulation server supply voltage, while meeting server test by regulation output voltage four jiaos, the test needs such as draw partially, for server test, there is vital role.

Embodiment
With reference to the accompanying drawings, by embodiment, the utility model is further illustrated:
Embodiment 1:
The server power supply that output voltage is adjustable, comprises reference voltage operation circuit, also comprises a resistance regulation and control plate, and the structure of described resistance regulation and control plate comprises a rheostat Rt, is parallel to reference voltage circuit.
By the resistance regulation and control plate designing and the reference voltage operation circuit of corresponding output voltage connected (just designing inside when reference voltage circuit is Power Management Design), like this, adjusting resistance device knob position changes the size of rheostat access resistance, thereby change the resistance of reference voltage circuit, resistance has become, and output voltage also can change naturally.
Embodiment 2:
On the basis of embodiment 1, described resistance regulation and control plate also comprises a fixed value resistance R3, and Rt connects with rheostat.It is to regulate and control voltage in order to change resistance value that rheostat is set, and it is in order to prevent short circuit that fixed value resistance is set.
Embodiment 3:
On the basis of embodiment 1 or 2, described rheostat RT is knob rheostat 2.Be convenient to staff's regulating resistance size.
Embodiment 4:
On the basis of embodiment 3, for 12V, 5V, the different voltage of 3.3V, corresponding resistance regulation and control plate is set respectively, and knob rheostat 2 is separately set to respectively to outer casing of power supply 1.In order to facilitate the regulation and control of voltage, at outer casing of power supply place, with the knob rheostat of tag identifier regulation voltage, facilitate personnel to operate, and the corresponding knob of regulation and control 12V, 5V, 3.3V is identified.
In circuit theory diagrams, resistance R 3 is in parallel with resistance R 2 after connecting with rheostat Rt, then after connecting with R1, connects 12V output, and other end ground connection, by adjusting the difference of R1 and R2 resistance, obtains respectively 12V, 3.3V, 5V voltage.By adjusting knob rheostat, change loop resistance value, thereby change output voltage.
