4 FAQs about Port communication power supply cabinet AC DC integrated

How many power supplies can a 24U cabinet support?

For single cabinet requirements, two cabinet heights are of-fered. The 24U cabinet can accommodate up to four 30kW DC power supplies or up to four 30kW regenerative DC loads. Power levels to 120kW are supported by this cabinet size. For requirement up to 240kW, the 42U cabinet is needed.

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 voltage does a DSL power system supply?

The DSL power system may supply both higher voltage analog line drivers and amplifiers (typ. +/-12V) and several low voltage supplies required by the digital ASIC (+5V, +3.3V, +1.8V, +1.5V).

How many DC buses can a multi-cabinet system have?

The DC bus is directly accessible on specific connection points (screws). The multi-cabinet solu-tions can have up to three DC buses which are connected in parallel from cabinet to cabinet via cables. The construction of the cabinets ensures high safety for per-sonnel.
