Abstract
The utility model discloses a multi-output regulated power supply. An alternating current power supply is connected to a transformer, a rectifier and a filter in sequence, wherein one path of the output end of the filter is connected to a 7805 voltage stabilizer and one potentiometer, and the other path of the output end of the filter is connected to a 7905 voltage stabilizer and another potentiometer. By adopting the multi-output regulated power supply, 220V alternating current is changed into 10V alternating current through the transformer, and then the 10V alternating current is rectified and filtered through the rectifier and the filter and is sent to the first corner of the 7805 voltage stabilizer of which three terminals are fixed and the third corner of the 7905 voltage stabilizer; the 7805 voltage stabilizer and the 7905 voltage stabilizer have the main advantages that the output voltages are stable, and the voltages of +/-5V and +/-15V are respectively output. The multi-output regulated power supply has a simple structure and a wide voltage output range.
Description
Technical field
The utility model belongs to power technique fields, relates to a kind of multichannel output stabilized voltage power supply.
Background technology
Electronic equipment, instrument etc. all require a reliability height, efficient height, constant voltage dc source that volume is little.Adopting under the situation of direct current supply, generally all earlier will import direct current and become high-frequency current with inverter, become required voltage with transformer after rectification be direct current, then by the stable output voltage of switch voltage-stabilizing device acquisition.Shortcomings such as under the situation that adopts Alternating Current Power Supply, existing alternating current steady voltage plug exists technological obsolescence, complex structure, and output voltage is fixing.
Summary of the invention
The purpose of this utility model provides a kind of multichannel output stabilized voltage power supply, and output voltage range simple in structure is wide.
The technical solution adopted in the utility model is, a kind of multichannel output stabilized voltage power supply, AC power is connected with transformer, rectifier, filter in turn, and filter output one tunnel is connected with 7805 pressurizers and potentiometer, and another road of filter output is connected with 7905 pressurizers and potentiometer.
Multichannel output stabilized voltage power supply of the present utility model, to be that the 220V alternating current becomes the rectifying and wave-filtering that 10V passes through rectifier, filter then by transformer, send three ends to fix first jiao and the third angle of 7905 pressurizers of 7805 pressurizers, the major advantage of 7805 pressurizers and 7905 pressurizers is that output voltage is fixed, and exports the voltage of positive and negative 5V, positive and negative 15V respectively.It is simple in structure, and voltage output range is wide.
Description of drawings
