Problems solved by technology

[0007] According to the above configuration, connecting the storage battery 3 and three DC-DC converters 50 to a single secondary drive circuit B not only complicates and increases the size of the secondary drive circuit B, but also if the DC-DC converter 50 fails, There is a problem that the DC voltage output through the DC-DC converter 50 cannot be taken out even in normal (normal)
[0008] In addition, due to the DC-DC converter 50, the efficiency of the primary switching power supply circuit is multiplied by 75-80% of the efficiency of the secondary DC-DC converter 50 to obtain an overall efficiency of about 55-64%. the problem of energy loss
[0009] In addition, when replacing the cooling fan of the power supply unit, since the drive of the cooling fan is stopped by completely removing the cooling fan, there is a possibility that a finger may accidentally touch the rotating cooling fan blade during the work of removing the cooling fan. problem of injury
In addition, it is conceivable to carefully remove the cooling fan to avoid injury, but it takes a lot of time and labor to replace the cooling fan, so it is necessary to improve

Abstract

This invention provides a power supply device, in which, a cooling fan is freely mounted in an encasing containing the power supply circuit a protecting part can freely change positions between the following positions: contacting the position where the fan can't be dismantled and blocking the position where the face can be dismantled, setting blocking parts contacting and stopping the protection part moving towards the position can't be dismantled.

Description

technical field [0001] The present invention relates to a power supply device that can quickly constitute an uninterruptible dual power supply device. The output of the DC power supply drives the load. In particular, uninterruptible dual power supplies that can be diverted to operate highly important machines such as precision machinery and automatic machinery in the fields of crime prevention, disaster prevention, communication, information (computer servers, FA personal computers, etc.), medical care, etc. The power supply unit for the device. Here, a power outage refers to a case where the supply of electric power (current) is cut off, for example, a case where the power supply from an electric power company is cut off, and a case where the power supply is cut off due to tripping, unplugging, or disconnection, etc. . Background technique [0002] When the above-mentioned power supply is used for example for a computer server, etc., it is necessary to constitute an unin...
