Bel Power Solutions TET4000 titanium efficiency 4 kW power supply

Bel Power Solutions & Protection introduce the TET4000 Series, a 4000W power supply designed to provide the highest efficiency (Titanium) power conversion for datacenters

The TET4000 series, a 4000W power supply designed to provide the highest efficiency (Titanium) power conversion for data centres built to Open Compute Project (OCP), Open Data Centre Committee (ODCC) or Central Office Re-architected to Data centre (CORD) standards. As the highest power 48VDC model in Bel Power’s power supply portfolio, this is one of very few 4000watt 48VDC server power supplies available as standard product.

Within the data centre ecosystem, the adoption of 48V for power distribution is accelerating as it can improve Power Usage Effectiveness (PUE), lower Total Cost of Ownership (TCO) and boost computing density and rack utilisation. The 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 data centre 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 530mm), Bel Power’s TET4000 series can convert standard AC mains power into a main output of 48VDC, which is programmable from 42 to 58VDC, with power-factor correction (PFC). Both the normal and reverse airflow models are hot-pluggable and feature parallel operation with active current sharing or analogue 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.

With an always-on +12V 60W standby output and a CAN communication interface for monitoring, control and firmware update via bootloader, these power supplies meet international safety standards and display the CE-Mark for the European Low Voltage Directive (LVD) and have patents pending.
