ASTEC power supply Overview: ASTEC power supply is a device that provides electric energy.
Because it can convert other forms of energy into electrical energy, we call this device that provides electrical energy a power source.
Generators can convert mechanical energy into electrical energy, while dry batteries can convert chemical energy into electrical energy.
The generator and the battery themselves are not charged. Their two poles have positive and negative charges respectively, and the voltage generated by the positive and negative charges (
Current is formed by the directional movement of charge under the action of voltage)
The electric charge conductor already exists. To generate current, you only need to add voltage. When the two poles of the battery are connected to the conductor, the positive and negative charges are released in order to generate current. When the charge is exhausted, the Lotus will disappear. Dry batteries and so on are called power supplies.
The device that turns alternating current into direct current through transformer and rectifier is called rectifier power supply. Electronic devices that can provide signals are called signal sources.
The transistor can amplify the signal sent in front and transmit the amplified signal to the circuit behind.
Transistor can also be regarded as a signal source for the following circuits. Rectifier power supply and signal source are sometimes called power supply.
ASTEC power supply is a device that provides power to electronic equipment, also known as a power supply, which provides electric energy needed by all components in a computer.
The size of the power of the power supply, whether the current and voltage are stable, will directly affect the working performance and service life of the computer.
ASTEC power supply is a closed independent component installed in the main chassis. Its function is to supply the system version and floppy disk in the main chassis with stable direct current through a switching power supply transformer, use system components such as hard disk drives and various adapter expansion cards.
Generally speaking, one power supply is broken and the other backup power supply replaces its power supply.
Hardware availability can be enhanced by providing battery backup for nodes and disks.
Uninterruptible power supplies supported by HP, disks and power supply circuits should be connected in such a way that mirrored copies are connected to different power supplies.
The root disk and its corresponding node should be powered by the same power supply circuit. In particular, cluster lock disks (Used as an arbiter when reorganizing a cluster)
There should be redundant power supplies, or it can be powered by power supplies outside the nodes in the cluster.
The HP representative of ASTEC power provides detailed information on the power, disk, and hardware layout of the cluster.
Power supply at present, many disk arrays and other rack-mounted systems contain multiple power inputs, which should be deployed as different power inputs on the equipment connected to independent circuit devices with two or three power inputs, in this way, under normal circumstances, as long as there is no more than one faulty circuit, the system can continue to operate normally.
ASTEC power supply is applied to high frequency pulse width modulation technology. The difference from General switching power supply is that its output must be the same frequency and same phase AC voltage as the input side.
Its output voltage wave types include quasi-square wave, ladder wave, sine wave, etc. The uninterruptible power supply on the market pulls out the power storage source and charger, which is a switching AC stabilized power supply with good stability, it has strong control function and is easy to realize intelligence. It is a very promising ac stabilized power supply.
However, due to its complex circuit and high price, the promotion is slow.
It has introduced a large number of ARTESYN power supply, COSEL power supply and imported LED screen power supply, providing a large number of products and services for users in various industries. Many outstanding professional manufacturers in the world have close cooperation.
At the same time, the company makes full use of the advantages of the international Internet, not only can provide users with * a wide range of product selection opportunities, obtain * Excellent character ratio, but also provide users with scientific and technological information quickly.
