DCDU is designed for high-current DC power distribution in communication base stations and telecom cabinets. As a reliable dc power 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.
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.
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.
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.
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.
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.
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.
