Wherein: 1, supply module; 11, power input terminal; 12, Switching Power Supply; 13, power output terminal; 2, output port.

Embodiment

For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 1, a kind of power supply stack module of network power supply, comprising: multiple supply module 1 and an output port 2; Wherein: each supply module 1 all can realize 220V electric main to be converted into 48V DC power supply, as shown in Figure 1: each supply module 1 comprises the power input terminal, Switching Power Supply and the power output terminal that are electrically connected successively; Power input terminal is for connecting 220V electric main, and Switching Power Supply is used for 220V electric main to be converted into 48V DC power supply, and above-mentioned multiple power output terminal converges on a wire, this wire is connected with output port 2; As preferred embodiment, described Switching Power Supply comprises the first rectification circuit, inverter circuit, transforming circuit and the second rectification circuit that are electrically connected successively; Described power input terminal is electrically connected with the input of the first rectification circuit; The output of described second rectification circuit is electrically connected with power output terminal.

The first rectification circuit in above-mentioned specific embodiment, inverter circuit, transforming circuit and the second rectification circuit are relatively more conventional circuit, therefore repeat no more its concrete circuit structure herein.

Further: in above-mentioned specific embodiment, the power output of each supply module is 24W.

Operation principle of the present utility model is: 220V electric main is converted into 48V DC power supply by each supply module 1, then a specific power is exported, such as 24W, be specially and power input terminal 1 is connected with the electric main of 220V, now, the electric main of 220V becomes the DC power supply of 220V after the first rectification circuit of Switching Power Supply, the DC power supply of described 220V becomes the AC power of high frequency through inverter circuit subsequently, then the AC power of high frequency becomes the low-voltage alternating current power supply of 48V through transforming circuit, the low-voltage alternating current power supply of last 48V becomes the low-voltage dc power supply of 48V by the second rectification circuit, during use, user can according to the power number on output port 2 needed for power consumption equipment, and then calculate need several above-mentioned supply module 1 can realize work, such as, when power consumption equipment power demand is 96w, now, four supply modules 1 and 220V electric main can be connected, each supply module 1 can provide a power to be the 48V DC power supply of 24W for output port 2 subsequently, then, four supply modules 1 can provide a power to be the 48V DC power supply of 96W for output port 2.

Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
