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

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 cabinets increases. 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 the future.
