The TET3200-12-069RA 3,200-W titanium-efficient ac-dc front-end power supply can convert 277 Vac into a main output of 12 Vdc for powering intermediate bus architectures (IBA) in high-performance and high-reliability servers, routers and network switches and applications. It delivers a power density of 34 W/in3 and achieves titanium efficiency (>96% efficient at 50% load) in a package measuring 69 x 40.5 x 555 mm (2.72 x 1.60 x 21.85 in). The ac-dc stage uses soft-switching resonant techniques to reduce component stresses, providing increased system reliability and high efficiency, in conjunction with synchronous rectification. It also has a dc input voltage range of 180 to 410 Vdc.
