Abstract

The invention relates to a control method and system for a voltage-stabilized power supply with a differential amplification link, and belongs to the technical field of voltage-stabilized power supply systems, and the method comprises the following steps: when an adjusting knob and a voltage-stabilized power supply switch are locked, preferentially obtaining an adjusting instruction; and then the adjusting knob is unlocked based on the adjusting instruction. Because the adjusting knob and the voltage-stabilized power switch are both in the locking state, a user cannot operate the adjusting knob and the voltage-stabilized power switch, when the user uses the voltage-stabilized power supply, the user can preferentially obtain an adjusting instruction and then unlock the adjusting knob based on the adjusting instruction, and at the moment, the voltage-stabilized power switch is still in the locking state; therefore, a user has to operate the adjusting knob firstly, so that the user is prevented from neglecting operations such as resetting (zeroing) of the adjusting knob when using the voltage-stabilized power supply, and the condition that a fault occurs when the direct-current voltage-stabilized power supply is used is reduced.

Description

technical field [0001] The present application relates to the technical field of regulated power supply systems, and in particular, to a control method and system for a regulated power supply with differential amplification links. Background technique [0002] At present, stabilized voltage supply (stabilized voltage supply) is an electronic device that can provide stable alternating current or direct current for the load, including two categories: alternating current stabilized power supply and DC stabilized power supply. When the grid voltage or load fluctuates instantaneously, the regulated power supply will compensate the voltage amplitude with a response speed of 10-30ms to stabilize it within ±2%. [0003] In the related art, a DC regulated power supply is usually used to supply power to the load. When in use, connect the two output lines of the DC regulated power supply to the positive and negative poles of the load, and then rotate the voltage adjustment knob to the ...
