Tattoo power supply's working principle

Tattoo power is adevice to provide electronic equipment power , also called tattoo power supply, it provides all parts needed electricity in the tattooing. If the size of the tattoo power supply power, current and voltage is not stable, will directly affect the work of a tattoo machine performance and service life.

Tattoo power supply is a kind of installed  closed independent components, its role is to alternating current (ac) through a switch tattoo power transformer in for 5 V, 5 V, + 12 V, 12 V, such as stable dc + 3.3 V, to supply the mainframe system version, floppy disk, hard disk drives and various adapters use expansion card and other system components. Popular speaking, is that a tattoo power supply is broken, another backup tattoo power supply to replace the power supply. For the node and provides the battery backup disk to increase the availability of hardware. The HP support continuous tattoo power supply (UPS), such as HP PowerTrust, but beware of instantaneous power lost. Disk and the connection of the power supply circuit should make a copy of the mirror respectively connected to different tattoo power supply. The root disk and its corresponding node should be by the same tattoo power supply circuit of power supply. In particular, the cluster disk lock (when restructuring cluster is used as the arbitrator) there should be a redundant Yu Wenshen power, or, it can be seen by the cluster nodes outside of the tattoo power supply. Your HP representative can provide about cluster tattoo power supply, disk and LAN hardware layout details. At present a lot of disk array and other frame system containing multiple tattoo power input, they should be deployed as a different tattoo power input devices connected to the with two or three independent tattoo power input circuit device, so that, in general, no more than one, as long as the failure of circuit system can continue to work normally. Therefore, if all the hardware in the cluster have 2 or 3 tattoo power input, insist on at least three independent circuit, to ensure that no single point of failure in cluster of circuit design.

I hope the above can have the help about knowing tattoo power supply's working principle, this article from the http://news.tattoodiy.com/ knowledge about tattoo power supply can click on the url to understand.
