Abstract

The invention discloses a DC power supply and a control circuit thereof, comprising a power supply body and a T-shaped bracket, wherein the upper side of the horizontal part of the T-shaped bracket is provided with a power supply body, and the lower end of a vertical part of the bracket is equipped with a supporting rod, one end of which is fixed on the lower side of the horizontal part of the bracket. The top of the power supply body is fitted with a hanging ring, and there is a rope connecting the hanging ring and the suspension loop. The middle part of the left and right sides of the power supply body is mounted with a plurality of through-holes for heat dissipation. The upper part of the through-hole is provided with a rain shield, and the front side of the power supply body is equipped with a hinge-connected door that can open and close. The device can adjust DC voltage of the DC power supply from 3V to 15V continuously, with a maximum current up to 10A. The device has temperature compensation characteristics, and adopts high-precision standard voltage source integrated circuit TL431, enabling a higher stabilized voltage precision.

Description

technical field [0001] The invention relates to a power supply, in particular to a direct current power supply and its control circuit. Background technique [0002] DC power supply is a device that maintains a stable and constant current in the circuit. As an important supporting equipment of the power system, DC power supply has been widely used in important places such as power plants, substations, satellite communication stations, nuclear power plants, and subways. DC power supplies are widely used indoors and outdoors. , but the DC power supply is generally connected with a large number of high-sensitivity original devices. If it is placed outdoors alone, various failures are prone to occur during operation. Construction requirements, and it is inconvenient to disassemble and move. For this reason, those skilled in the art have deduced a DC power supply and its control circuit from the problems mentioned in the background above. Contents of the invention [0003] Th...
