pdu power supply refers to "Power Distribution Unit", which means "power distribution unit" in Chinese, which is the power distribution socket for the cabinet. PDU is a product designed to provide power distribution for cabinet-mounted electrical equipment. It has a variety of series specifications with different functions, installation methods and different socket combinations. It can provide suitable rack-mounted equipment for different power environments. Power distribution solutions.

The application of PDU can make the power distribution in the cabinet more neat, reliable, safe, professional and beautiful, and make the maintenance of the power supply in the cabinet more convenient and reliable.

Development History

In the early days, foreign PDU was the mainstream and the price was relatively expensive. In the past few years, there have also been companies in China that specialize in R&D and production of this type of cabinet-specific power socket (PDU). Due to the high level of domestic PDU professional manufacturing in recent years, while ensuring excellent quality, the price has obvious advantages over foreign brands. It has quickly become the mainstream of the domestic PDU market. In recent years, with the development of the market, many PDU manufacturers have rapidly emerged in China, with research and development and imitation coexisting, and the quality varies. (You should be careful when choosing PDU products. It is recommended to choose products that have a long research and development time and have undergone market testing).

Later, there were gradually corresponding PDUs for each market segment, such as basic type, SNMP type, RS485 MODBUS type, cloud PDU, and IoT PDU.

Product Advantages

Compared with ordinary power strips, the advantages of cabinet sockets (PDU) are mainly reflected in: more reasonable design arrangements, stricter quality and standards, It has long safe and trouble-free working time, better protection against various types of leakage and overcurrent and overload, frequent plugging and unplugging movements and is not easily damaged, small heat rise, and more flexible and convenient installation. It is suitable for customers in industries with strict power requirements. It also fundamentally eliminates potential safety hazards such as frequent power outages, burns, and fires caused by poor contact and small load of ordinary power strips.

Easy to install on a 19-inch standard cabinet or rack, occupying only 1U of cabinet space, supports horizontal installation (standard 19-inch), vertical installation (installed parallel to the cabinet column), and can also be applied to other applications occasion. Multiple protection: Built-in multi-level surge protection device provides stronger protection, and also provides filtering, alarm, power monitoring and other visual devices. Internal connection: The jack reed is made of phosphor bronze, with good elasticity and excellent contact, and can withstand 10,000 More than twice the number of plugs and pulls; the connection methods between socket modules all use threaded terminals and plug-in terminals, and the socket ends are equipped with convenient devices such as fixing bolts for fixing cables. More intelligent options, easy management and remote control: The product can optionally add digital display, abnormal alarm, network management and other functions to highlight the intelligence of the product and improve its usability and ease of management. Multiple circuit protection lightning strike and surge protection: Maximum impact current resistance: 20KA or higher; Limit voltage: ≤500V or lower; Passed professional testing by Beijing Lightning Protection Testing Center, can be used as equipment-side fine surge protection Alarm protection: LED Digital current display and full-range current monitoring filter protection with alarm function: With fine filter protection, ultra-stable output pure power supply Overload protection: Provides two-pole overload protection, which can effectively prevent problems caused by overload.

Features

1. High safety factor and cost saving

The power supply managed through PDU has overload power-off protection and multiple circuit protection functions to prevent Overload, high temperature, lightning strikes, surges and other hazards can maximize the safety factor of the product. In addition, this product can help users achieve unattended operation, save labor costs, effectively reduce management and maintenance costs, and is cost-effective.

2. Real-time power monitoring, automatic alarm protection

pdu can monitor power parameters such as supply voltage, current, active power, reactive power and frequency in real time, making it easier for users to master and manage various power supplies. equipment. When the system fails or the total load current exceeds the system setting value, an alarm will be automatically sent through SMS, email and phone calls.

3. Support remote control and facilitate management

PDU can be connected to the LAN or the Internet. Users can remotely control the PDU through the computer and query the power supply of each device on its downlink port. , connect, disconnect or restart, completely breaking the constraints of distance and geography.

4. Flexible policy management

Users can customize configuration strategies based on the usage of various power equipment. Based on the user's policy management and monitoring events, this product supports centralized management and automatic cycle control. It can manage several devices simultaneously in one interface and independently set the power switching cycle, which is convenient and practical.

5. Electricity measurement, energy consumption evaluation

PDU can manage the power consumption of electrical equipment, calculate the power factor, and evaluate the energy consumption of electrical equipment. If the power factor is low, power is lost during the transmission process, and power consumption suddenly surges, the PDU can adjust the power consumption status of the device through settings, and alert users through text messages, emails, etc.
