Inverters & Converters
TT Electronics provides a suite of four converters and one emergency inverter to a large military transport aircraft. Each of these units were custom designed to meet the aircraft’s specific requirements.
The converter suite consists of a 500VA, 1kVA, 2x 3kVA units providing 115v/230v, 50/60Hz output derived from the aircraft in a 3 phase, variable frequency ac input. Designed to meet the requirements of DO254 DAL C.
The inverter supplies 3.5kVA, 400Hz ac emergency power to support critical flight control in the event of an aircraft main ac power failure during emergency RAT deployment. Designed to meet the requirements of DO254 DAL B.
Motor & Generator Control
The company’s experience in motor & generator control extends to the development of a high power (14kVA) 550Vdc, dual BLDC motor controller derived from the aircraft variable frequency ac power.
This was designed for operation within extreme environmental conditions, 40,000ft in a non conditioned bay, to meet the requirements of DO254 & DO178 B DAL B.
Power Supplies & Distribution
TT Electronics is able to design & manufacture custom made power supplies at PCB, module and/or LRU level.
Our units cover a wide range of power levels & complexity including software control and in-house, custom designed, solid state circuit breakers.
TT Electronics has designed an independent power supply to provide power to deploy the emergency floatation system on board helicopters in the event of an aircraft main power system failure.
