Dual power supply system for communication equipment room
A dual source PDU is a specialized power distribution unit designed to provide a redundant power supply for critical systems. It connects to two independent electrical feeds, ensuring continuous power delivery even if one source fails. Power factor corrected (PFC) AC/DC power supplies with load sharing and redundancy (N+1) at the front-end feed dense, high efficiency DC/DC modules and point-of-load converters on the back-end. Although these terms sound similar, they refer to distinct concepts. This article explains the differences and helps you understand which approach fits your application. These two power lines usually come from substations in different directions or from different busbars in the same substation with two or more incoming lines. You can also adopt the distributed power supply. Managing two separate power sources through dual power automatic transfer switch systems represents a fundamental advancement in electrical safety and system reliability.
