4 FAQs about American Communication Power Supply Cabinet AC DC Integrated

What is a DC power system?

A complete DC power system with distributed power output and battery backup all included in one unit. Two types available: Type 1 which combines DC power and batteries into a single cabinet, and Type 2 where batteries are separate (for larger systems). Primary DC output voltages in 24V, 48V, 125V, or 240V classifications.

What is AC/DC power rectification?

AC/DC power rectification using modular SMRs offers redundancy and expandability. Integrated DC distribution eliminates the need for a separate distribution panel. Battery charging with battery circuit breaker included. Provides complete DC uninterruptible power supply (UPS) functionality.

What types of AC inputs are available?

Worldwide AC input with continuous operation from 85VAC to 270VAC, 47-440Hz to include 115VAC / 230VAC, AC power in all foreign countries, AC aircraft power, AC generator and DC to AC Inverters. Not limited to 95VAC. See KEY FEATURES. Wide DC input range of 9 to 36VDC to include 12VDC, 24VDC, 28VDC aircraft power, HMMWV and DC generators.

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.
