High capacity modular supply system for telephone users

The authors describe the planning criteria used to produce a small-size redundant power supply system. This type of system is equipped with display, microprocessor autodiagnosis, and remote supervision with sinusoidal main input and output according to telephone requirements. It is shown that in order to achieve monitoring of all information in a high-performance system without compromising reliability, a solution that comprises many high-performance modules that operate in redundant parallel must be chosen. These requirements are a starting point for the realization of the rectifier module, thus adopting switching technology in a single conversion and inserting the system in a standardized measurement container. Entrusting the diagnosis element to the microprocessor and its peripherals completes the system, thus obtaining complete control of the system as well as both local and remote monitoring of all information. It is seen that the application of this power system is directed to all telecommunication systems that require uninterrupted power supply as all those systems that require a high level of reliability and performance from the power system.<>
