Astronics has designed a new Dual Frequency Converter Unit (DFCU) that provides a simple solution for outfitting business jets and large VIP jets with power outlets that can handle almost any type of electrical device. The new DFCU delivers 4,000 watts of 115 or 230 volt AC to passenger power outlets.
Part of the Astronics Empower line of business jet electrical products, the DFCU is equipped with solid-state electronic circuit breaker (ECB) technology. This enables “programmable ECB outputs that can be custom configured to each cabin, eliminating the need for a secondary distribution panel and saving both cost and weight,” according to Astronics (Booth N1721).
Another advantage offered by the Astronics DFCU is that it provides higher power output for running galley and lavatory appliances and equipment, including such items as hair dryers, shavers, microwave ovens, mixers, etc.
Power output of the DFCU outlets is either 115 VAC at 60 Hz or 230 VAC at 50 Hz. The unit offers up to 10 programmable ECB outputs, configurable at 115 VAC with seven outputs at 15 amps and three at 10 amps or at 230 VAC with 10 outputs at 10 amps. The DFCU can report faults and status via Arinc 429 and RS-485 buses. LRU weight including a 1ATR short mounting tray is 29.2 pounds.
Safety features include remote on/off switch, overcurrent and overvoltage protection circuits, load-shedding including a programmable priority scheme to prevent overloading and an intelligent thermal-management system. The DFCU meets RTCA DO-160G standards.
