DESCRIPTION
This field proven Transformer Rectifier Unit (TRU) can deliver
150 amps of power in an unpressurized environment or up to
200 amps in a pressurized environment.
This design has been successfully operating in the field since
1997 and has an MTBF of greater than 50,000 operating
hours. Already in use on business jets, this upgraded unit is
finding new uses aboard many different platforms and can
reliably provide you with the power that you need for your
system.
This TRU is one of many that Crane Aerospace & Electronics
provides as the world’s leading supplier of TRUs and ATRUs
for commercial aircraft. We offer field proven, exceptionally
reliable power solutions for both commercial aerospace and
military applications.
