The role of the energy system
The primary role of the energy system is to supply the equipment that make up the telecom infrastructure with power with very specific characteristics. In addition, it provides backup power. In these ways, the energy system guarantees up-time for the telecom networks and thus secures the operators’ revenue-generating services.
THE MAIN COMPONENTS OF THE ENERGY SYSTEM
Rectifiers
Electronic equipment cannot operate on the current coming out of the mains. All such equipment consequently depends on power supplies that can convert the high-voltage, alternate mains current into a lower-voltage, direct current. This is the main function of the rectifier, which is a key component in a DC energy system. Typically, a rectifier will convert the mains 110/220/240/480 V AC to 48 V or 24 V DC, before it is fed into the telecom equipment. A telecom power system may consist of a number of rectifiers, depending on the size and requirements of the application.
Batteries
Batteries provide DC power of the appropriate voltage in case of mains power failure. The batteries make up the bulkiest part of the system and also the most vulnerable. Consequently, efficient battery monitoring and controlled charging is key to stable operations.
Monitoring system
This is the “brain” of the system, which monitors performance and allows an operator to control the system – either direct through displays, keypads and controls – or on a computer connected physically to the network or remotely, e.g. via the Internet.
