What is the output voltage of a communication base station?
Assume the output voltage of a communication base station’s power system is 48V, with the LLVD threshold set to 40V. When the mains power fails and the battery starts supplying power, the power system continuously monitors the output voltage through the voltage detection circuit.
What is a base station power cabinet?
The base station power cabinet is a key equipment ensuring continuous power supply to base station devices, with LLVD (Load Low Voltage Disconnect) and BLVD (Battery Low Voltage Disconnect) being two important protection mechanisms in the power cabinet.
What is a low profile power supply?
Low profile power supply design usually includes printed circuit board (planar) power transformers and output inductors and surface mount input and output capacitors. Multiple output power supplies are often implemented with a multi-output flyback converter.
What voltage does a DSL power system supply?
The DSL power system may supply both higher voltage analog line drivers and amplifiers (typ. +/-12V) and several low voltage supplies required by the digital ASIC (+5V, +3.3V, +1.8V, +1.5V).
What is a 3G base station converter?
In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.
What is a preferred power supply architecture for DSL applications?
A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.
Selecting the Right Supplies for Powering 5G Base Stations
