A PDU (Power Distribution Unit) power socket is a power distribution manager that provides both power distribution and management functions. It is the first and most crucial component for the operation of multiple devices, and the quality of the PDU directly impacts the performance of the devices.

The PDU series cabinet socket power protector is designed based on IEC standards, specifically for the fine protection of sensitive equipment powered by single-phase AC. PDU power cabinets are used at the device end as the third level of power protection, preventing damage from transient overvoltage caused by lightning strikes or electronic interference.

The power protection lightning arrester of the PDU power cabinet adopts a two-stage series-connected protection system, with a maximum current carrying capacity of up to 20kA and a voltage protection level as low as 800V. It is compatible with various national standard plugs and power specifications, and features a recoverable overload protection device, perfectly combining the lightning arrester with the power socket.

In today's society, with the rapid development of the internet and increasing bandwidth demands, the confidentiality and security of networks have become more pressing.

The PDU power socket is a new type of socket device with reliable safety standards. It is used in mobile phones and other small electronic devices to receive DC power, and is equipped with a pin in the center of the plug hole.

PDU Industry Background

Power Distribution Unit (PDU): Initially, foreign PDU brands were mainstream and expensive. In recent years, domestic companies specializing in the research and production of cabinet power sockets (PDU) have emerged. Due to the high manufacturing level of these domestic PDUs, they offer competitive prices while ensuring excellent quality, rapidly becoming the mainstream in the domestic PDU market. However, with the development of the market, several PDU manufacturers have appeared, leading to a mix of research and imitation, with varying quality. When choosing PDU products, it is important to be cautious and prefer products that have undergone long-term market testing.

PDU Product Features

· Interface Compatibility: Modular power socket holes that conform to international standards, meeting the diverse needs of customers from various countries, with multiple output socket types and IEC output sockets for compatibility with different imported equipment plugs.

· International Standard Rack-Mount Installation: Convenient installation in 19-inch standard racks, occupying only 1U of rack space. Supports both horizontal and vertical mounting.

· Multiple Circuit Protection: Lightning strike and surge protection, with a maximum surge current of up to 20kA and voltage limitation ≤ 500V, providing precise surge protection for the equipment end.

· Modular PDU: Ideal for dynamic data centers aiming for high power and space efficiency, modular PDUs can be distributed across racks, offering great flexibility and reducing cable clutter.

Considerations for Selecting a PDU:

1. Choose According to Specific Needs: Select a product that matches your specific requirements.

2. Choose a Reputable Manufacturer: Ensure that the manufacturer has a good reputation and experience in the industry.

3. Quality Certifications: Always check the manufacturer's qualifications and the product's quality certifications.

4. After-sales Service: Ensure that comprehensive after-sales service is available.

PDU Power Rating Explanation

The rated power of a PDU refers to the total output power of all its outlets. The size of this power depends on the following key factors, ordered as follows:

1. The plug's carrying capacity ≥ the total switch's carrying capacity ≥ the external wire's carrying capacity = the internal wire's main line carrying capacity ≥ the total overload protection's carrying capacity ≥ the total output socket's carrying capacity ≥ the PDU's rated power.

This means that if the carrying capacity of any single point in the above key factors increases, it will not increase the rated power of the PDU. However, if the carrying capacity of any single point decreases, it will cause the rated power of the PDU to drop to the smallest value of the carrying capacity of any one of these key points.

Relationship Between PDU Output Socket Forms and Rated Power:

When using a PDU, you may encounter situations where the device plug does not match the PDU socket. Therefore, when customizing a PDU, it is essential to first confirm the form of the device plug and the device's power. The carrying order is as follows:

PDU output socket power = device plug power ≥ device power.
