270 V DC system - a highly efficient and reliable power supply system for both telecom and datacom systems

摘要

A 270-V DC power supply system is superior to the conventional 48-V DC system or 200-V AC system because of its high reliability, high supply efficiency and low cost, especially as the power consumption of telecom and datacom equipment cabinetsincreases. Introducing 270-V DC system will require the development of several power supply components in the telecom and datacom equipment cabinet. Therefore, the appropriateness of the 270-V DC system depends on the power consumption of cabinets in thefuture.
