Power Supply accuracy refers to the accuracy of regulated power supply. The accuracy is the degree of proximity between the observed value and the true value. When each physical quantity is to be expressed in numerical value, a standard must be established first and a unit must be selected. In the structural design, different precision should be set for different links, and higher precision should be set for sensitive links, so that higher overall working precision can be obtained through more economical methods.
matters needing attention :Power supply is a device that provides power to electronic equipment, also known as power supply, which provides the power required by all parts of the computer. The power of the power supply, the stability of the current and voltage will directly affect the performance and service life of the computer. Computer power supply is a kind of closed and independent component installed in the main box. Its function is to change alternating current into 5V, - 5V, + 12V, - 12V, + 3.3V and other stable direct current through a switch power transformer, so as to supply the system components in the main box, such as system version, floppy disk, hard disk drive and various Adapter expansion cards. Uninterruptible power supply (UPS) supported by HP, such as HP powertrust, can be protected against instantaneous power failure. The connection mode between disk and power supply circuit should make the mirror copy connected to different power supplies ZD. The root disk and its corresponding nodes should be powered by the same power circuit
