Since 1958, Crane Aerospace & Electronics has led the way in the development of reliable aircraft AC-DC power conversion. Our line of Transformer Rectifier Units (TRUs) provide affordable, efficient and reliable power conversion while meeting today's new stringent power quality requirements.

Isolated passive AC to DC conversion for DC power

• Input voltage: 115 Vac or 230 Vac 
• Output voltage: 28 Vdc or 270 Vdc
• Output current: 10 A to 400 A
• Efficiency: 85 to 92%+
• Power Factor: >0.96 (depending upon configuration and power level)
  • Total harmonic distortion (THD): 12 pulse <12%; 24 pulse <5%
  • High current overload capability (typically 150% for 2m and 200% for 5s)
• Compatible with pulsed dynamic loads
