Weidmüller power supply is the main equipment to realize electric energy conversion and power transmission. It is a product with high technical content, wide knowledge, and fast updating..This product has been widely used in agriculture, energy, transportation, transportation, information, aviation, aerospace, shipping, national defense, education, culture and other fields..In the current information age, the above-mentioned various industries are developing rapidly and abnormally, and at the same time, they put forward more and higher requirements on the power supply industry..Such as energy saving, power saving, material saving, shrinkage, weight reduction, pollution prevention, environmental improvement, reliability, safety, etc..This forces power supply workers to continuously explore in the power supply research and development process, seek various related technologies, and make qualified power products to meet the requirements of all walks of life, thus invisibly driving the rapid development of related technologies..And it is precisely because of the rapid development of these technologies that has promoted the development of the power supply industry.
The computer power supply is a closed independent component installed in the main box. Its function is to change the AC power to 5V, -5V, +12V, -12V, +3 through a switching power transformer.3V and other stable DC power supply to supply system components such as system version, floppy disk, hard disk drive and various adapter expansion cards in the main box.Generally speaking, one power supply is broken, and another backup power supply replaces its power supply..The availability of hardware can be enhanced by providing battery backup for nodes and disks.HP-supported uninterruptible power supply (UPS), such as HP PowerTrust, can prevent instantaneous power loss.The connection between the disk and the power supply circuit should be such that the mirrored copies are connected to different power sources..The root disk and its corresponding node should be powered by the same power circuit.In particular, the cluster lock disk (used as an arbiter when reorganizing the cluster) should have redundant power, or it can be powered by a power source other than the nodes in the cluster.An HP representative can provide detailed information about the cluster’s power, disk, and LAN hardware layout.At present, many disk arrays and other rack-mounted systems contain multiple power inputs. They should be deployed as different power inputs on the equipment connected to independent circuit equipment with two or three power inputs. In this way, in general, as long as there is If there is no more than one faulty circuit, the system can continue to operate normally.Therefore, if all hardware in the cluster has 2 or 3 power inputs, at least three independent circuits are required to ensure that there is no single point of failure in the circuit design of the cluster.Generators can convert mechanical energy into electrical energy, dry batteries can convert chemical energy into electrical energy.The generator and the battery are not charged. Their two poles have positive and negative charges respectively. The positive and negative charges generate voltage (current is formed by the directional movement of charges under the action of voltage). The charge conductor is inherently present in it, and it needs 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 dissipated, the charge is exhausted (pressure) is dissipated..Dry batteries, etc. are called power sources.The device that converts alternating current into direct current through a transformer and a rectifier is called a rectifier power supply..The electronic device that can provide the signal is called the signal source.The transistor can amplify the signal sent from the front, and then transmit the amplified signal to the subsequent circuit..The transistor can also be regarded as a signal source for the following circuit.Rectified power supply and signal source are sometimes called power supply.
“Such power adapters are usually purchased parts from outside, rather than produced by the manufacturer, and the manufacturer does not have the ability to verify whether its safety performance meets the requirements of the exporting country..”The relevant staff of the Ninghai Inspection and Quarantine Bureau analyzed that most of the products used with the power adapter are safe and extra-low voltage products, but the safety of its use during the charging process must be paid attention to..First of all, it is necessary to control the purchase of power adapters. You should choose a professional power adapter manufacturer, try to choose the model that has passed the product certification of the exporting country, and require the supplier to provide a certificate of conformity for each batch of power adapters purchased..Secondly, we must strictly control the acceptance of orders.Export companies should actively pay attention to foreign power adapter safety standards, master the latest European and American standards for dielectric strength, structure, creepage distance, electrical clearance, etc., and strictly review the requirements of the client’s relevant standards when receiving orders, and find design defects Communicate with the client in time and avoid blindly organizing production.So as not to lose too much due to small losses and lose at the “source” of the product.Weidmüller power supply
