The invention discloses a power supply and a system. The power supply comprises a first sub-power supply group and a second sub-power supply group. The first sub-power supply group comprises at leastone first sub-power supply, the positive electrode of each first sub-power supply is grounded, and the negative electrode of each first sub-power supply is connected to the negative electrode of electrical equipment. The second sub-power supply group comprises at least one second sub-power supply, the negative electrode of each second sub-power supply is grounded, and the positive electrode of each second sub-power supply is connected to the positive electrode of electrical equipment. According to the invention, the technical problem that the price of a special power supply customized for a galvanometer in a laser marking machine is multiple times of that of a common power supply and the corresponding manufacturing cost is thus increased in the prior art is solved.
Description
technical field [0001] The present invention relates to the field of power supply configuration, in particular to a power supply and a system. Background technique [0002] In the related art, there is a very important component in the laser marking machine equipment—the vibrating mirror. The main function of the galvanometer is to control the marking shape, area control or font outline definition and glyph shape when marking text. It is the key component of laser marking. When the galvanometer is working, it has very special requirements for the power supply. It is not an ordinary AC 220V power supply, nor is it a DC 24V power supply. Its requirements for power supply voltage are: +15V, GND, -15V. It requires simultaneous positive voltage, ground, and negative voltage to supply power at the same time to operate. This requires the power supply provided to have such a special supply voltage. However, this voltage is not an ordinary universal voltage, so special customiza...
