Power supply control system

Abstract

The invention discloses a power supply control system, which comprises an AC voltage power supply circuit, a storage battery power supply circuit, a switching module and an output circuit. The output end of the AC voltage power supply circuit and the output end of the storage battery power supply circuit are connected with the switching module; and the switching module is connected with the output circuit. The AC voltage power supply circuit comprises an anti-interference filter circuit, a transformer voltage-reduction circuit, a rectification and filtering circuit and a DC voltage regulator circuit, which are connected in sequence. The storage battery power supply circuit comprises a 24V battery module, an anti-interference filter module and a charging monitoring module, which are connected in sequence. The switching module is provided with a priority power supply mode. The storage battery power supply circuit power supply is the optimum power supply mode. The system is provided with the AC voltage power supply circuit and the storage battery power supply circuit; and in precision equipment or emergency equipment, the storage battery power supply circuit is used in priority, and power is supplied through the control power source, thereby guaranteeing normal operation of the system and power supply demand of the equipment.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to a power supply control system. Background technique [0002] With the development of modernization in our country, the construction of various types of industrial buildings is accelerating development. Some equipment has higher requirements for power supply. During the operation of the equipment, power failure cannot occur. For equipment powered by AC alone , Sudden power failure will have a serious impact on the normal production of the equipment, therefore, the use of a single power supply cannot meet the requirements of the equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a power supply control system for precision equipment or emergency equipment, and supply power through the control power supply to ensure the normal operation of the system and the power supply requirements of the equipment. [0004] To ac...
