What is a PDU power socket?
PDU(PowerDistributionUnit) is a power distribution manager with power distribution and management functions. PDU power socket is the first and closest component of many devices, and the quality of PDU directly affects every device. PDU series cabinet socket type power protection arrester is designed according to IEC standard, which is specially used for fine protection of sensitive equipment of single-phase AC power supply. Applied to the equipment side, as the third-level protection of power supply, it protects the equipment from transient overvoltage caused by lightning strike or electronic interference. This power protection arrester adopts two-stage series protection, the maximum flux can reach 20kA, the voltage protection level can be as low as 800V, the input and output are compatible with multinational standard plugs and various power supplies, and it has a recoverable overload protection device, which perfectly combines the arrester with the power plug board.
PDU power socket is a new type of socket equipment with reliable safety factor. It is a power socket for receiving DC power in various small electronic machines such as mobile phones, and there is a pin plug in the center of the plug jack.
Characteristics of PDU power socket
1, PDU power sockets are easy to install and maintain, and PDU power sockets can be installed and fixed in various ways.
2.PDU power socket has the local or online detection and early warning function of current and voltage, and has the protection functions of leakage prevention, lightning protection, overload and surge.
3. Because PDU power socket is safer and more reliable than ordinary power socket.
4.PDU power socket fundamentally eliminates the frequent power failure, burning, fire and other security risks caused by poor contact and small load of ordinary power sockets.
5. The kit material of 5.PDU power socket is phosphor copper, which has been finely processed.
6.PDU power sockets are produced and designed according to the international general structure, and are widely used in various standard and non-standard cabinets. Compared with ordinary power sockets, PDU power sockets can be applied to sensitive equipment system devices. PDU power socket has the advantages of PDU technology, high working efficiency, strong anti-interference ability and reliable performance.
7. The reliable contact of 7.PDU power socket is much greater than that of ordinary power socket, and the life of unipolar plug-in is more than 5000 times, which is much higher than that of ordinary power socket. PDU power socket has very good connectivity and conductivity.
Difference between PDU power socket and ordinary socket
1. Load power: The cable configuration load of ordinary sockets is relatively weak, and most of them are nominally rated as10A; ; 1.5mm2 cable, a few manufacturers will nominally 16A4000W. According to the national cable standard, it is difficult for ordinary sockets to really reach more than 4000W under any configuration. It can be seen that it is difficult to meet the requirements of the rapidly growing computer room. PDU(POWERDISTRIBUTIONUNIT) undoubtedly solves this problem to a great extent, because any part of it can be customized conditionally, which can completely meet the safety of the electrical environment in the computer room. At present, industrial plugs are more and more widely used in PDU, and their current can meet more requirements such as 16A, 32A, 65A, 125A, so it is very wrong to use ordinary non-professional sockets in cabinets.
2. From the material point of view: ordinary is generally plastic, and PDU is all metal. If the load is too large, PDU has fire protection function, but ordinary socket does not. Because PDU is a metal shell, it has anti-static function and protects sensitive electronic equipment from electrostatic hazards. Thereby protecting the stable operation of the equipment.
3. Functionally, ordinary sockets only have functions such as power overload and general control, and the output of jacks is also monotonous; PDU not only has many functions (such as lightning protection, master switch, overload protection, current and voltage display, remote monitoring function, online detection of smoke temperature and humidity, etc.). ), and the format of the output module can be reasonably matched and selected according to the specific situation. There are national standards, American standards, international IEC, German standards, etc. )
4. Service life: ordinary sockets are generally 2-3 years. The plugging and unplugging is about 4500-5000, and the PDU socket is made of superconducting metal material-tin (phosphor) bronze. It has good wear resistance and conductivity, and the temperature rise is only 20 degrees, which is far lower than the national standard of 45 degrees, effectively preventing components from heating. Hot-swappable 10000, with a service life as high as 10 years, which is more than 5 times that of ordinary sockets.
Due to the requirements of high professional design and material selection standards, the total carrying capacity of PDU is much larger.
At present, there are nearly 100 manufacturers of ordinary sockets in China. Either way, the wires of ordinary sockets are usually 0.5, 0.75, 1.0, 1.5 square meters and other specifications. Most sockets equipped with these specifications will be rated as10a; . There are also 1.5mm2 cables, and some manufacturers will mark 16A/4000W. In fact, this point is somewhat debatable. According to the cable standard BVV3* 1.5mm, the rated current carrying capacity of the cable is 13A.
No matter what configuration, it is difficult for the rated load power of ordinary sockets to really reach more than 4000W W, and obviously it is difficult to meet the high-current power demand of cabinets 16A, 32A and 63A, so it is strange that ordinary non-professional sockets have not responded for a long time.
PDU power distribution unit: steel plate or profile box has high strength, and PDU input and output unit, functional configuration, modular structure and installation mode can be freely combined. Fully customized PDU protection against lightning, leakage, overload and circuit breaker; The on-line monitoring and early warning function of current, voltage and other electricity consumption environment is realized through local area network or network. Ensure a safe electricity environment and more convenient and reliable power supply maintenance. Frequent power failure, burning, fire and other security risks. The problems caused by poor contact and small load of ordinary power sockets are fundamentally eliminated.
