Abstract
The utility model provides an industrial control stabilized voltage supply, comprising a transformer, a rectifier circuit and a filter circuit. The power supply comprises a casing and a fixing slot is arranged on one side of the casing of the power supply. The transformer, the rectifier circuit and the filter circuit are arranged in the casing and a voltage-stabilizing circuit and a current foldback circuit are arranged in the casing. An input end and an output end are arranged on the casing and the transformer is a high frequency switch transformer. The utility model adopts a casing of the power supply which can combine the transformer and the circuits together, so has the advantages of reducing the bulk greatly, facilitating the fixing in the electricity control cabinet, avoiding the mistake of welding the wire on the spot and ensuring the product quality. Further, a slot is arranged on the casing, which can work by lightly stopping when fixing. The utility model adds the voltage-stabilizing circuit and the current foldback circuit which improve the working reliability of the power supply. The utility model adopts a switch transformer which reduces the volume of the power supply, improves the work efficiency and lowers the cost.
