Numerical control mobile power source

Abstract

The invention discloses a numerical control mobile power source. The numerical control mobile power source works as follows, first, a starting signal is triggered by a touch button of a touch button circuit to start up, after the start-up, each module is first initialized to be ready for work, and the initialization mainly includes a sleep circuit, the touch button circuit, a liquid crystal display circuit, an alarm circuit, a liquid crystal backlight circuit, a voltage sampling circuit and a current sampling circuit. After a circuit switch is turned on, the initialization is completed, and the program begins to enter a main working state. First, the voltage and current are collected through a voltage collecting circuit and a current collecting circuit, and a judgment is made on whether the output is connected with a load, or whether the touch button circuit is at work. The numerical control mobile power source of the invention has the functions of being portable and capable of use asa power bank, adopting long-life touch buttons and automatic shutdown, and the like, products can be conveniently debugged on the spot without plugging in 220V, and the numerical control mobile powersource can be used anywhere.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a digitally controlled mobile power supply. Background technique [0002] Most traditional power supplies use knob potentiometers to adjust voltage and current. Knob potentiometers will be affected by temperature to produce errors in output voltage and current. Moreover, the adjustment speed of knob potentiometers is slow and the positioning is inaccurate. There is a problem that one adjustment is not in place. Use It sounds troublesome, but the CNC power supply does not have the above problems. For example, CN104410277A, CN103731051A in Jinan, China, and similar patents all use digital control DC power supply to work, but intelligently realizes CNC power supply, cannot be used for mobile use, and cannot be used as a power bank. Lithium batteries cannot be used for power supply, and low-power solutions such as automatic shutdown cannot be realized. There are al...
