Power Distribution Unit | China Manufacturer

Types of Power Distribution Unit

Basic Rack PDUs

Basic Rack PDUs mainly meet the most basic needs of data center cabinet power distribution, ensuring that socket standards, socket quantity, power rate and status indication, local switch control, overload and surge protection, size and installation method meet user needs.
Metered Rack PDUs

In addition to meeting the most basic power distribution needs of the cabinet, Metered Rack PDUs can also monitor and measure the electrical parameters of the input and output ports of the PDU. In addition to meeting local metering, it can also be connected to the platform to realize the configuration of all cabinets in the computer room. Centralized monitoring and management of electricity. In addition, sensor interfaces are reserved to monitor the environment such as temperature and humidity, water immersion, access control, and smoke in the cabinet.
Smart PDUs

In addition to meeting the most basic power distribution needs of the cabinet, Switched Rack PDUs can also monitor the electrical parameters of the PDU's input and output ports, as well as monitor environmental parameters such as temperature and humidity, water immersion, access control, and smoke in the cabinet. In addition, remote on-off control of the output port can also be achieved.
Automatic Transfer Switch(ATS)

ATS is mainly used to automatically switch to the backup power supply when the main power supply of important equipment in the cabinet fails to avoid power outage of key power equipment, including servers, switches, and storage devices. In order to ensure the continuity and reliability of power supply, Kean ATS switching time can be accurate to within 10ms.
Direct Current Distribution Unit(DCDU)

DCDU is mainly used for power supply and protection of communication base station - 48VDC electrical equipment. The maximum input current can reach 250A, and the maximum output current of the output connector exceeds 40A. Each output can be equipped with an optional fuse to provide overload protection. It is also equipped with four Level 10kA lightning protection module. At the same time, the intelligent DCDU has electrical monitoring functions and can be connected to the platform for centralized management and control.
Power Cords

The power cord is mainly used to connect the PDU output socket and the electrical equipment. Because the plug and socket standards between the PDU socket and the electrical equipment are not uniform, or the cable length and diameter are not up to standard, the last 1 meter of the computer room power distribution system It troubles many users. We can equip the appropriate power cable according to the socket standard between your electrical equipment and the PDU. The socket standards, wire lengths, and wire diameters at both ends of our power cables can be customized as required.
Waterproof Industrial Electrical Connector

Industrial connectors are mainly used to connect power distribution cabinets in computer rooms and cabinet PDUs. Industrial connectors not only require reliable connections, but also require large current carrying capacity, flame retardancy, and waterproofing. The maximum voltage exceeds 480V, and the maximum current of a single core is 125A.

How Power Distribution Units Improve Electrical Efficiency and System Reliability

1. Port-level precise measurement and control, energy consumption visualization;

2. Three-phase balance optimization: By adjusting the equipment position, the unbalance degree is controlled within 5%;

3. Accurately identify inefficient equipment, optimize load distribution in a targeted manner, and save energy and reduce consumption;

4. Multi-path redundant independent power supply, clapping switching time < 20ms;

5. Integrate multiple sensors to achieve intelligent fault early warning;

6. Comprehensive safety protection, achieving multiple monitoring and protection measures such as overload, overvoltage, lightning protection and arc prevention.
