DCDU - 12B high - performance DC power distribution unit

DCDU - 12B is a high - performance DC power distribution unit, mainly designed to provide stable and reliable -48V DC power distribution for telecom equipment such as base stations. It is a key component in the power supply system of communication networks and is widely used in various base station scenarios.

1. Core Specifications & Parameters

   Parameter Category	Specific Details
   Input Performance	It has a nominal input voltage of -48VDC, with an input voltage range of -38.4VDC to -57VDC and a maximum input current of 160A. It supports M6 dual OT terminals for input and can adopt two input modes: 180A or 280A, matching 1 or 2 16mm² power lines respectively.
   Output Performance	It provides 10 - way -48VDC output, each with a rated current of 30A, totaling 10*30A. The output terminals include 6 large quick - connect terminals and 4 small quick - connect terminals. The large ones are compatible with 2.5 - 10mm² power lines, while the small ones are suitable for 2.5 - 4mm² power lines. All 10 output circuits are equipped with fuse protection functions, and the circuit voltage drop does not exceed 0.5V.
   Physical & Protection Specifications	Its weight is 1.65kg. The size (widthheightdepth) without mounting ears is 442mm42mm65mm, and with mounting ears is 482.6mm42mm65mm. It meets the 19 - inch standard 1U rack - mount size. The surge protection capacity reaches 10KA for differential mode and 20KA for common mode, effectively resisting lightning damage.

    

2. Product Features & Application Scenarios
   • Strong Adaptability to Equipment & Scenarios: It is compatible with multiple models of cabinets and subracks, such as BTS3900, BTS5900, and APM5930 (DC). It can supply power for configurations like 1BBU + 6RRU + 1FAN or 4BBU + 1*FAN. It is well - suited for power distribution needs of indoor and outdoor macro base stations, micro base stations, and distributed base stations, and can also provide power for OSN series optical transmission equipment, routers, and switches.
   • Convenient Installation & Practical Design: It supports both 19 - inch standard rack installation and wall - mounting. The 10 quick - connect terminals allow on - site wiring, which brings great convenience to on - site construction and maintenance. When more than 3 RRUs need to be powered, it can be switched to the 2 - way 16mm² input mode to meet the increased power demand.
