Excelitas designs and manufactures multi-phase transformer rectifier units and light weight auto-transformer rectifier units suitable for airborne and shipboard applications. TRUs are a high-reliability solution for applications requiring reduction of input line current harmonics, such as:
- Avionics and aircraft systems
- Military shipboard electronics
Key Features:
- Standard 3-phase AC input voltages, 50/60 Hz, 400 Hz or 360-800 Hz (wild frequency)
- 28V, 270V 320V or custom DC output voltages
- Power levels 100 W to 25kW
- High reliability with >100,000 hours mean time between failure (MTBF)
- 15-phase (30-pulse) rectification requires less external filtering
- Isolated design or weight-saving non-isolated “ATRU”
Electrical Performance:
Peak to peak output ripple <5% of output voltage
Power factor typically >.99
Designed to meet DO-160G and MIL-STD-1399 Section 300 harmonics
Environmental Conditions:
- Baseplate temperature range of -55°C to +85°C
