AC and DC common industrial television camera power supply

摘要

This high case is about the power supply device of industrial TV camera.In order to solve the problems of the former AC and DC power supply, the power input part combines the static current diode into Brett terrain.Connect the symmetrical two sides to the power connection port (21, 21 ')One side took overOn the other hand, when it is connected to the AC input of the smooth circuit element (L1) and the capacitor (C1), when the DC input is made, even if the operation of the power supply circuit changes to the normal power supply, it will lead to the fault caused by the disconnection of the power supply, and the power supply of the AC and DC power supply is transferred As a public utility, it has useful and economic benefits.
