| description | The utility model discloses an input voltage-limiting circuit of a live display power supply. The input voltage-limiting circuit comprises a three-phase power supply, wherein the three-phase power supply is connected with a high-voltage sensor, the three-phase power supply is in series connection with three voltage-stabilizing circuit units constituted by current-limiting resistors and voltage-stabilizing diodes, and the three voltage-stabilizing circuit units are connected in parallel. The whole input voltage-limiting circuit disclosed by the utility model can not affect the display of a display screen or the normal working of an electricity testing plug because the voltage is too high or too low. The input voltage-limiting circuit of the live display power supply is simple and integrated, the operation is safe and reliable, the voltage of the input circuit can be effectively reduced, and the input voltage-limiting circuit can be widely applied to the field of live display devices. |
