Bel Power Solutions Releases TET2500 Series Titanium Efficiency Power Supplies

Bel Power Solutions has released the TET2500 Series, 2,500W power supplies, offering Titanium level efficiency to servers, storage and networking equipment.

With AC-DC power-factor-corrected (PFC) and high voltage DC-input variants, TET2500 Series power supplies provide a main output of 12VDC for powering intermediate bus architectures (IBA).

Measuring just 86mm × 40mm × 195 mm (3.39in × 1.57in × 7.68in), the TET2500 Series provides a high-efficiency and feature-rich power source for servers running web and email applications, databases, games or providing storage, as well as for file servers, routers and network switches.

This high-performance computing equipment is being used in the rollout of applications and services such as edge computing, blockchain processing, real-time communications, Cloud services and virtualised applications in new and upgraded data centres.

Both the normal airflow (TET2500-12-086NA) and reverse airflow (TET2500-12-086RA) models are hot-pluggable and feature parallel operation with active current sharing or analogue bus and full digital controls for improved performance. The TET2500 Series delivers a power density of 62W/in3 and meets 80 Plus Titanium efficiency.

Both models incorporate resonant-soft-switching technology and interleaved power trains to reduce component stresses, providing increased system reliability and very high efficiency. These power supplies also provide an always-on +12V 24W standby output and I2C communication is up to 400kHz.

Innovations incorporated into the TET2500 Series are currently pending patents. The TET2500 Series meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD).

The TET2500-12-086NA is available from Digi-Key, Arrow and Allied. Samples of either TET2500 Series (normal and reverse airflow) are available upon request.

Power in railway rolling stock originally involved traction, lighting and rudimentary signalling with typically raw 110VDC from the on-board batteries.
