Bel Power Solutions announced the expansion of their portfolio to include the TET3200-12-069RA, a 3200 W Titanium efficient AC-DC front-end power supply that can convert up to 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.
The TET3200 delivers a power density of 34 W/in3 and achieves Titanium efficiency (>96% efficient at 50% load) in a compact 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 very high efficiency, in conjunction with synchronous rectification. It also has a DC input voltage range of 180-410 VDC. An active OR-ing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant power systems. These power supplies are hot swappable and can be connected in parallel with active digital current sharing. An always-on +12 V 36 W standby output is also provided.
