4 FAQs about Metro Communication Power Supply Cabinet AC DC Integrated

What types of power systems are used in communications infrastructure equipment?

Communications infrastructure equipment employs a variety of power system components. 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.

What is a preferred power supply architecture for DSL applications?

A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.

What is a low profile power supply?

Low profile power supply design usually includes printed circuit board (planar) power transformers and output inductors and surface mount input and output capacitors. Multiple output power supplies are often implemented with a multi-output flyback converter.

What is a VoIP DC-DC converter?

A VoIP DC-DC converter uses a less complex single high-power output transformer design (typ. 250-500W) to buffer the main -48V distribution bus. This minimizes the cost and the capacitance of bulk capacitors required to hold up the distribution bus voltage by narrowing the operating voltage to 43-57V from the traditional 36-72V range.
