Dual Frequency Converter Unit

Dual Frequency Converter Unit

The Dual Frequency Converter Unit (DFCU) is a revolutionary departure from traditional converters. With its ability to produce either 115 or 230 volts AC, the DFCU can support passenger and utility power anywhere in the world an aircraft operates.

Additionally, the DFCU utilizes the latest Solid-State Electronic Circuit Breaker (ECB) technology. It uses ten (10) programmable ECB outputs to custom configure the cabin to meet customer requirements.

The benefits are numerous. Whether for OEM or aftermarket installation, dual frequency means never having to remove and replace equipment regardless of where the aircraft operates during its lifetime.

By utilizing ECBs along with GFI-equipped outlets at each output, cabin designers can eliminate the use of heavy and costly distribution panels, wire and installation labor.

For passengers, it means a constant source of power. Rather than disabling the entire system for a tripped breaker, the self-protection aspects of the DFCU and the ability to reset a tripped outlet means no interruption of service. This keeps passengers productive and entertained.
