Titanium Efficiency 4kW Power Supply for OCP, CORD and Datacenters

Bel Power Solutions has announced the TET4000 Series, a 4kW power supply designed to provide the highest efficiency (Titanium) power conversion for datacenters being built to Open Compute Project (OCP), Open Data Center Committee (ODCC) or Central Office Re-architected as a Datacenter (CORD) standards. The TET4000 Series is the highest power 48Vdc model in Bel Power's power supply portfolio and one of very few 4kW 48Vdc server power supplies available as standard product.

The adoption of 48V for datacenter power distribution is accelerating within the datacenter ecosystem as it can improve Power Usage Effectiveness (PUE), lower Total Cost of Ownership (TCO) and boost computing density and rack utilization.

The new TET4000 Series is designed to provide peak efficiency over 97.5 per cent, classified as Titanium level, the highest efficiency classification for power supplies. These new 48V datacenters and central offices are equipped with high performance servers and super computers running scalable and distributed computing of large volumes of data.

Housed in a compact form factor (69 x 40.5 x 530 mm), Bel Power's TET4000 Series can convert standard ac mains power into 48Vdc, nominal, programmable from 42- to 58-Vdc, with power-factor correction. Both the normal and reverse airflow models are hot-pluggable and feature parallel operation with active current sharing or analog bus and full digital controls for improved performance.

The TET4000 Series delivers a power density of 44W/in3 and incorporates soft-switching resonant techniques in conjunction with synchronous rectification, providing increased system reliability and very high efficiency.
