Voltage/Frequency Power Converter (Contact Us)
The L-3 Communications Power Systems Group AN/BSY-2 Voltage/Frequency Power Converter is a water-cooled, five-channel voltage/frequency changer for use in weapon and combat system electrical power conversion.

288 kW ACSSFC (bulletin 436)
The ACSSFC from L-3 Communications Power Systems Group is the second-generation air-cooled, solid-state frequency converter which supplies precise, reliable power for the U.S. Navy's most advanced and sophisticated weapon system AEGIS. A direct descendant of the U.S. Navy MK84, liquid-cooled, solid-state frequency converter, the ACSSFC is the class standard on the Arleigh Burke Class Aegis Destroyers.

L-3 Power Systems Group's new family of Air-Cooled Frequency Converters (ACFC) represents the next leap forward in refined, stable and reliable power delivery to central and distributed 400 Hz systems such as weapons, fire control, ECM, sonar and avionics. L-3 Power Systems Group ACFCs comply with MIL-STD-1399 requirements for Type III power and STANAG 1008, Edition 8, and are compatible with existing shipboard data busses. The ACFC family includes units with ratings of 75 kW, 100 kW, 125 kW, 150 kW and 175 kW.

ACFC (bulletin 444)
The ACFC is a new ruggedized COTS derivative of L-3 Power Systems Groups' highly successful 288 kW frequency converter which is the class standard in the Arleigh Burke Class Aegis Destroyers. The ACFC produces the precise 400 Hz that complies with the stringent systems requirements of both MIL-STD-1399 for Type III power and STANAG 1008, Edition 8.

Mini Frequency Converter Model 4056 (bulletin 6411)
The L-3 Communications EUROATLAS lightweight solid-state 400 Hz to 60 Hz Miniature Frequency Converter has been designed for commercial airborne applications and is applied for razor outlets in all AIRBUS airplanes except A 300 and A 310. The unit converts aircraft primary AC power of 115 Volt, 400 Hz into 115 and 230 Volt, 60 Hz. As integrated within the lavatory module behind the service cabinet no extra protection is required and no housing is necessary. For other applications (e.g. Crew Rest Compartment) the unit is available with enclosure as Model 4056-A.

Static Frequency Converter Model 3025 (bulletin 6412)
The L-3 Communications EUROATLAS lightweight solid-state 400 Hz to 60 Hz Frequency Converter has been designed for commercial airborne application and is in operation on various AIRBUS planes. The unit converts aircraft primary AC power 400 Hz into 110 V, 60 Hz and supplies the socket outlets in the passenger compartment.
