A socket is also arranged on the shell, the socket is connected with a cable, and the cable is connected with the output end of the power transformer and the output end of the voltage stabilizing circuit through a double-pole double-throw switch. All the surfaces of the shell except the bottom surface are respectively equipped with a TEC plate connected with the output end of the voltage stabilizing circuit, and the cold side of each TEC plate is arranged towards the inside of the shell. Output of the power supply equipment can be switched between AC and DC, and the power supply equipment has a better radiating effect when outputting low-voltage direct-current power.
Description
Technical field
The invention belongs to technical field of electronic products, be specifically related to a kind of power supply with alternating current-direct current handoff functionality.
Background technology
The operating voltage of a lot of electronic device is not line voltage, but line voltage will be become required voltage through processing of circuit and carry out work, and therefore we just need corresponding power-supply device to change ordinary city piezoelectric voltage.The power supply that a lot of electronic equipment uses is low-voltage DC, and its inside of power-supply device producing this direct voltage generally comprises: power transformer, rectification circuit, filter circuit and voltage stabilizing circuit.In life, some electronic equipment does not need low-voltage DC, but uses low-voltage AC to get final product work (such as some application heating wire carry out the electronic product etc. of heating warm-keeping).Therefore, when only needing low-voltage AC to carry out work, we just can try every possible means a transformation function of the power transformer of use power-supply device inside to realize required voltage requirement, thus the work of the rectification circuit of power-supply device inside, filter circuit and voltage stabilizing circuit is eliminated, these Circuits System are made to be in resting state, because this reducing the loss of these Circuits System, the bulk life time of power-supply device is extended.
In addition, we also wish power-supply device work process in have better radiating effect with can be reliable and stable work.
Summary of the invention
The output that the object of the invention is to overcome power-supply device in prior art is without alternating current-direct current handoff functionality and wish that power-supply device can have the problem of better radiating effect.
For this reason, the invention provides a kind of power supply with alternating current-direct current handoff functionality, comprise housing and interior power supply circuit thereof, interior power supply circuit comprises: power transformer, rectification circuit, filter circuit and voltage stabilizing circuit; The output of power transformer is connected with the input of rectification circuit, the output of rectification circuit is connected with the input of filter circuit, the output of filter circuit is connected with the input of voltage stabilizing circuit, described housing is also provided with socket, described socket is connected with cable, and described cable is connected with the output of power transformer and the output of voltage stabilizing circuit by double-point double-throw switch; The upper surface of described housing, front surface, right surface, left surface and rear surface are provided with the TEC plate be connected with the output of voltage stabilizing circuit, and the cold side of described TEC plate is all arranged towards the internal direction of housing.
Above-mentioned double-point double-throw switch is arranged on the upper surface of housing.
Beneficial effect of the present invention: this power supply with alternating current-direct current handoff functionality provided by the invention, comprise housing and interior power supply circuit thereof, interior power supply circuit comprises: power transformer, rectification circuit, filter circuit and voltage stabilizing circuit; The output of power transformer is connected with the input of rectification circuit, the output of rectification circuit is connected with the input of filter circuit, the output of filter circuit is connected with the input of voltage stabilizing circuit, described housing is also provided with socket, described socket is connected with cable, and described cable is connected with the output of power transformer and the output of voltage stabilizing circuit by double-point double-throw switch; The upper surface of described housing, front surface, right surface, left surface and rear surface are provided with the TEC plate be connected with the output of voltage stabilizing circuit, and the cold side of described TEC plate is all arranged towards the internal direction of housing.Instant invention overcomes the problem of output without alternating current-direct current handoff functionality of power-supply device in prior art; In addition, the present invention makes power-supply device have better radiating effect when exporting low-voltage DC, and the present invention extends the useful life of power-supply device.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
