Abstract
The utility model relates to a switch power supply which comprises a casing, a control main board, a power supply input terminal, a power supply output terminal, a relay output terminal and a display screen. The power supply input terminal, the power supply output terminal, the relay output terminal and the display screen are respectively connected with the control main board, and then the control main board, the power supply input terminal, the power supply output terminal, the relay output terminal and the display screen are arranged in the casing. The switch power supply is convenient to use, and has the functions of warning, faulted relay output, and voltage and current displaying.
Description
Technical field:
The utility model relates to a kind of power supply, particularly a kind of Switching Power Supply.
Background technology:
Along with scientific and technical develop rapidly, require more and more higher to power supply reliability, capacity/volume ratio.Because the adjustment pipe of Switching Power Supply is operated in saturated and by state, thereby caloric value is little, power-efficient height (more than 75%) and saved the transformer of large volume.In addition, the most important thing is, its operating frequency height, high frequencyization makes the Switching Power Supply miniaturization again, and makes Switching Power Supply enter application widely, particularly in the application of high-technology field, has promoted miniaturization, the lighting of new high-tech product.Switching Power Supply more and more shows its superiority, and volume is little, reliability is high, is convenient to install and the combination dilatation, so more and more be widely adopted.
Existing Switching Power Supply lacks reports to the police or fault output, and owing to does not have voltage and current to show that the user can't know current detailed operation situation, uses very inconvenient.
Goal of the invention:
The purpose of this utility model is to provide a kind of relay easy to use, that have warning and fault to export, have the Switching Power Supply that voltage and current shows.
Summary of the invention:
For achieving the above object, the utility model is taked following design: this Switching Power Supply, form by housing, control main board, power input terminal, power output terminal, relay output end, display screen, described power input terminal, power output terminal, relay output end, display screen are connected described control main board respectively, again with described control main board, power input terminal, power output terminal, relay output end, display device in described housing.
Because the utility model adopts above technical scheme, the control main board of Switching Power Supply is handled the information of electric current and voltage, reports to the police or malfunction by the reaction of relay output end; The control main board of Switching Power Supply and the communication between the display screen show output voltage and output current.Like this, the user just can recognize the electric current and voltage and the operating state of Switching Power Supply more intuitively; The user can also utilize the warning of relay output end output and fault-signal to carry out circuit control as required, perhaps collects processor and carries out information processing.
Because the utility model adopts above technical scheme, reached easy to use, had and report to the police and the relay output of fault, have the purpose that voltage and current shows.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation
Embodiment:
As shown in Figure 1, this Switching Power Supply of the utility model, form by housing 1, control main board 2, power input terminal 3, power output terminal 4, relay output end 5, display screen 6, described power input terminal 3, power output terminal 4, relay output end 5, display screen 6 are connected described control main board 2 respectively, more described control main board 2, power input terminal 3, power output terminal 4, relay output end 5, display screen 6 are installed in described housing 1.
Because the utility model adopts above technical scheme, the information of 2 pairs of electric current and voltages of control main board of Switching Power Supply is handled, and reports to the police or malfunction by 5 reactions of relay output end; The control main board 2 of Switching Power Supply and the communication between the display screen 6 show output voltage and output current.Like this, the user just can recognize the electric current and voltage and the operating state of Switching Power Supply more intuitively; The user can also utilize the warning of relay output end 5 outputs and fault-signal to carry out circuit control as required, perhaps collects processor and carries out information processing.
Because the utility model adopts above technical scheme, reached easy to use, had and report to the police and the relay output of fault, have the purpose that voltage and current shows.
Below only be an embodiment of the present utility model, any based on equivalents of the present utility model all within protection range of the present utility model.
