Direct Current Distribution Unit (DCDU)
DCDU is a DC power distribution unit designed for communication base stations and 48VDC telecom equipment. It distributes stable DC power within base station cabinets while providing lightning protection and circuit safety for connected devices. As a compact dc pdu solution, it supports a maximum current of up to 125A and up to 10 output ports for reliable telecom power distribution.
In telecom applications, DCDU can be understood as a specialized dc pdu designed for 48VDC base station power distribution, while dc power pdu is a broader term that may cover different DC cabinet power distribution products.
Features of DCDU
01
Strong Current Carrying Capacity
DCDU is designed for high-current DC power distribution in communication base stations and telecom cabinets. As a reliable 48V DC distribution unit, it supports large input and output current while using high-quality phosphor bronze conductive components to ensure a large cross-sectional area, stable conductivity, and strong current carrying capacity.
02
Reliable Connector
The output connector adopts a screw-free shrapnel design, helping improve installation efficiency and connection stability for 48VDC communication equipment. This structure allows the direct current unit to support a maximum output of 40A per connector while maintaining reliable contact performance in long-term cabinet operation.
03
High Safety
The input circuit adopts a 10kA lightning protection design, and the output circuit is equipped with overload protection. When the rated operating current is exceeded, the fuse mechanism activates automatically to reduce fire risks and protect connected DC equipment. This makes the product suitable for use as a compact dc pdu in base station power distribution systems.
04
Intelligent Monitoring and Control Technology
DCDU not only meets basic power supply and distribution requirements, but can also be equipped with intelligent monitoring technology for centralized management of back-end DC power equipment. For telecom cabinets that require remote supervision, this dc power pdu helps monitor power status, improve operational visibility, and support safer maintenance.
DCDU FAQs
What is the maximum current of DCDU?
A DCDU is designed for high-current DC power distribution in telecom and communication base station cabinets. Depending on the project configuration, the maximum input current can reach up to 125A, helping the dc power distribution unit deliver stable power to multiple 48VDC communication devices.
How many ports can DCDU output at most?
A standard DCDU can support up to 10 output ports, making it suitable for 19-inch telecom cabinets, base station power systems, and other DC equipment cabinets. The number of output ports can be selected according to cabinet space, load requirements, and the number of connected devices.
Can DCDU achieve intelligent monitoring?
Yes. A DCDU can be equipped with intelligent monitoring functions to track electrical parameters of input and output ports, such as current, voltage, and operating status. This allows the dc power pdu to support centralized monitoring, easier maintenance, and safer operation in telecom power distribution systems.
Can a DCDU be customized for different telecom cabinets?
Yes. A dc power distribution unit can be configured according to project requirements, including input current, number of output ports, fuse protection, connector type, monitoring function, and cabinet installation needs. This makes it suitable for different telecom base station and communication power distribution projects.
What is a DCDU used for?
A DCDU is mainly used to distribute DC power inside communication base stations, telecom cabinets, and 48VDC power systems. It works as a direct current unit that connects power input, output circuits, fuse protection, lightning protection, and optional monitoring functions in one compact cabinet-level solution.
What is the difference between a DCDU and a DC PDU?
A DCDU is a dedicated DC distribution device commonly used in telecom base stations and 48VDC communication systems. A dc pdu is a broader term for DC power distribution products. In many telecom applications, DCDU can be considered a specialized dc pdu with protection, distribution, and monitoring functions designed for base station equipment.
Does a DCDU provide lightning protection?
Yes. The DCDU input circuit can adopt lightning protection design to help protect connected DC equipment from surge damage. It is especially useful in outdoor base stations, communication sites, and telecom cabinets where stable power supply and surge protection are both important.
