Transformer Rectifier Unit (TRU)/Auto-Transformer Rectifier Unit (ATRU)
This TRU (transformer rectifier unit) and ATRU (auto-transformer rectifier unit) is ideal for airborne and shipboard applications involving avionics and aircraft systems, and military electronics.
These units are high-reliability (greater than 100,000 hours mean time between failure) solutions featuring power levels of 100 W to 25 kW, standard 3-phase AC input voltages, and 28V, 270V, 320V, and custom DC output voltages.
These TRUs and ATRUs have a less than 5% peak-to-peak output ripple voltage and a power factor greater than .99 (typical). They’ve been designed to meet DO-160G and MIL-STD-1399 Section 300 harmonics standards.
Excelitas’ multi-phase transformer rectifier units and light weight auto-transformer rectifier units have a baseplate operating temperature range of -55oC to +85oC. Download the available datasheets and brochures for more information.
