The utility model has the advantages that, can with the adjustable DC of mainstream on the market the DC power module cooperation realizes that the voltage of wide region is adjustable. The control unit and monolithic or polylith DC the nimble combination of DC power module realizes the output of different power, and the after -separating is as independent unit module, can all the autonomous working, and the maintenance replaceability is good. It has a plurality of AD passageways and DA passageway in addition, can realize multichannel power output easily, mutual isolation between each way.
Description
Technical field
The utility model relates to programmable power supply survey technology field, particularly relates to a kind of modularization programmable power supply.
Background technology
Programmable power supply is a kind of intelligent power supply, it can be according to the energy needing to meet the specification for the offer of other equipment of varying environment, it is not only widely used in Auto-Test System, and can play an important role in industrial production and experimental study field as a kind of general power source.On market, major part programmable power supply is all based on the digital control power supply of single-chip microcomputer and DSP, it directly controls DC-DC converter by PWM or PFM and realizes output voltage and the regulation of electric current, programmable power supply kind in the market is many, and its performance indications such as adjustable range, control accuracy also have multiple choices, but it is sufficiently bulky, price is expensive, it is difficult to realize modular arrangements, and use and maintenance is poor.
Utility model content
The purpose of this utility model is to provide a kind of modularization programmable power supply, and modularized design, easy maintenance, rich interface, volume is little, flexible configuration, low cost.
To achieve these goals, the utility model have employed following technical scheme: a kind of modularization programmable power supply, including using the surface-pasted dual platen of SMT, is provided with control unit in described dual platen, and dual platen is provided with display button unit；Described control unit includes STC single-chip microcomputer and high accuracy D/A converter, is provided with DA chip in high precision in D/A converter；Described STC single-chip microcomputer is connected with display button unit；Described high accuracy D/A converter is connected with monolithic or polylith DC-DC power module.
Wherein, described dual platen is provided with RS422 interface and RS232 interface.
Wherein, described DA chip is by RS422 interface and RS232 interface and the interconnection of outer computer.
Wherein, described STC single-chip microcomputer is furnished with multiple AD passage and DA passage.
The beneficial effects of the utility model are: can coordinate with the adjustable DC-DC power module of main flow on market, it is achieved the voltage of wide scope is adjustable.
It can be by the control unit flexible combination of monolithic or polylith DC-DC power module and programmable power supply, it is achieved the output of different capacity, as independent unit module after separation, can work alone, and maintenance replaceability is good.
The power density ratio of power module uses the Switching Power Supply of discrete component much larger, and reliability is the highest, and therefore, it is the least that this scheme works it out programmable power supply volume, stable performance.
Additionally it has multiple AD passage and DA passage, can realize the power supply output of multichannel easily, mutually isolated between each road.
Accompanying drawing explanation
In order to be illustrated more clearly that the utility model embodiment technical scheme, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing only the utility model in describing below is in order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below the accompanying drawing used required in p-embodiment or description of the prior art is briefly described, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of the utility model protection.
A kind of modularization programmable power supply as shown in Figure 1, including using the surface-pasted dual platen of SMT, is provided with control unit in described dual platen, dual platen is provided with display button unit；Described control unit includes STC single-chip microcomputer and high accuracy D/A converter, is provided with DA chip in high precision in D/A converter；Described STC single-chip microcomputer is connected with display button unit；Described high accuracy D/A converter is connected with monolithic or polylith DC-DC power module.
Described dual platen is provided with RS422 interface and RS232 interface.
Described DA chip is by RS422 interface and RS232 interface and the interconnection of outer computer.
Described STC single-chip microcomputer is furnished with multiple AD passage and DA passage.
Control unit realizes man-machine interaction by display and keystroke interface, shows voltage x current numerical parameter, receives control instruction simultaneously.By RS422 interface and RS232 interface, DA chip realizes the interconnection with outer computer, thus realizes long-range power supply and control.DA chip output analog signal controls the voltage and current that DC-DC power module output is different in high precision.The voltage and current value of high-precision AD channel chip Real-time Collection output, to realize defencive function, these information is sent to display button unit for display by STC single-chip microcomputer simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
