Description

Electrical system

The utility model relates to the power supply of various devices, in particular, to chargers for mobile phones, electronic notebooks, handheld computers, laptops, players, etc.

A known power system, including a power source and a transition device in the form of a two-wire line (NOKIA 6210. Operation manual. Issue 2, M., 2001).

The known power supply system and the transition device can be used for a particular device only if there is a power source having certain electrical parameters (AC or DC voltage with a given level and polarity) required for this device.

The technical result from the use of the proposed power supply system and the transition device is the possibility of using the same power system for devices requiring reel with different electrical parameters.

The specified technical result is achieved in that in a power supply system including a power source and a transition device in the form of a two-wire line, the power source has two or more outputs with different supply voltages connected to the inputs of the supply voltage selection unit, the address input of which is an input for supplying information about the required power parameters, and the output is the output and the voltage is connected, and the transition device is sabzheno memory unit, the output of which is the output of information about the required parameters s power.

The specified technical result is also achieved by the fact that the transition device for the electric grease system, including a two-wire line, is equipped with a memory unit, the output of which is the output of information on the required power parameters. In FIG. 1 shows a functional electrical diagram of a system

power supply.

The power supply system comprises a two-wire line 1 with a memory unit 2, a power supply selection unit 3, a power supply 4.

The power system operates as follows. The output of the memory unit 2 is connected to the address input of the selection unit 3, and the two-wire line 1 is connected at one end to the output of the selection unit 3, and the other to the powered device. The connection can be made, for example, using pre-installed connectors. In this case, the information contained in the memory unit 2 on the electrical parameters of the power supply (for example, in the form of a voltage level or a digital code bearing the type number of the transition device) of the power supply device for which this transition device is intended, enters the selection block 3, which supplies voltage to the output power supply from the corresponding output of the power supply 4. As a result, the voltage required to power the selected device is supplied to the output of the supply voltage. The selection block 3 can be executed, for example, in the form of a switch, to the control input of which information from the output of the memory block 2 is supplied through a decoder.
