First of all, cabinet special PDU is also called cabinet special socket is usually called PDU, English full name power-distribution-unit, meaning POWER DISTRIBUTION UNIT. The PDU is generally designed for the 19-inch standard cabinet. It adopts a modular structure to ensure the power supply of important devices such as communications and electronics in the cabinet to avoid equipment damage caused by overvoltage and lightning induction. Although the PDU is a small device, but it is the longest working time of various devices, as long as the device is working, the PDU will be in the working state. If the quality of the PDU is not good, it may cause power failure or even fire, and its loss will be immeasurable.

Cabinet dedicated PDUs and common functions:

1, lightning protection, surge protection: maximum impact current: 20KA or higher; Limit voltage: ≤500V or lower.

2. Alarm protection: LED digital current display and full current monitoring with alarm function.

3, filter protection: with fine filter protection, output ultra-stable pure power supply.

4, overload protection: provide bipolar overload protection, can effectively prevent problems caused by overload.

5, anti-misoperation: PDU main control switch ON/OFF with protection grid, can prevent accidental closure, while providing optional dual.

6, modular design, with international standard jack, British standard jack, German standard jack, American standard jack and other different modules can be freely replaced to meet the different needs of multinational customers.

Of course, the cabinet special PDU power distribution unit also has advantages such as a wide range of use, high mechanical strength, safe and reliable use.
