HIGH RELIABILITY CONVERTERS FOR AIRBORNE APPLICATIONS RUGGED & EFFICIENT ATRU/TRU CONVERTERS For further information on our full product portfolio, please email us at: powersales@ttelectronics.com TT Electronics provides auto-transformer rectifier units (non-isolated) and transformer/rectifier units (isolated) optimised for minimum size and weight, and maximum reliability, solving many of the challenges inherent in airborne rectification.
- Wide range of sizes – 250W to 40kW+
- Application specific output voltages – 28/270/400/540 VDC are standard, voltages to 800 VDC can be accommodated
- Ultra-reliability – minimum component count provides extremely high MTBF for mission critical application and flight safety
- Defense and commercial aerospace applications – for internal and external power on commercial aircraft, radar and communications power on defence platforms
- Compliance to various power quality standards – DO-160G, MIL-STD-1399, MIL-STD-704
- Rugged design – for use with a wide range of temperatures and acceleration profiles. DO-160G, MIL-S-901, MIL-STD-167, MIL-STD-810
- Optimised size, weight and cooling – from time of initial design all performance characteristics are analysed for their impact on size, weight, temperature rise, efficiency. Convection, conduction and forced-air cooling www.ttelectronics.com - Available in wide side range - Ultra Reliable - minimal component count - Aerospace & Defence applications - Compliance to various power quality standards - Rugged design - Optimised size, weight and cooling
Features15 kW ATRU for new commercial aircraft applications www.ttelectronics.com This newly designed ATRU has been optimised for use aboard commercial aircraft and utilised to drive a powerful DC motor. Several design innovations are employed – a newly designed phase-shifting autotransformer topology, enhanced forced air cooling and DC filtering for improved motor performance. Fully DO-160 compliant, this package provides flexibility in ATRU design for other applications and power levels.
- Motor drive application – 400 VDC output, 15kW continuous. Filtered DC output for very low ripple (<0.1 V P-P with balanced line input). Diode switching profile selected for EMI emissions and lighting susceptibility compliance to DO-160
- Utilises newly designed transformer topology – along with efficient, low-weight heat-transfer approach previously designed and employed by TT Electronics
- Short development cycle – less than 16 weeks from time of order until delivery of qualification units
- COTS enclosure – ARINC 600 5-MCU standard dimensions
- Optimised weight – 32 lbs. for 15kW continuous
- Manufacturable – Transformer/diodes/filter inductor fully assembled prior to installation in enclosure Key Characteristics Input Voltage 200/115 V , 3 phase, 400 Hz per DO-160G Section 16 Cat A(CF) Output Voltage 400 VDC nominal unregulated Power 15kW continuous, 30 kW for 30 seconds, 45kW for 5 seconds Ripple <3 V peak – peak with unbalanced lines Efficiency > 97%, 50-100% load Power Quality DO-160G Section 16 Designation H Thermal Forced air cooling, 180 deg.
