Bel Power Solutions Releases Titanium Efficient Power Shelf for 48V Systems

Bel Power Solutions has released its SPSTET4 System (Power Modules, Shelf, Controller and Power Distribution Unit (PDU)).

These products are designed for systems and applications where AC-DC conversion from single-phase AC mains power to 54.5Vdc is required.

The SPSTET4 System is a complete computer rack power solution and includes:

  • SPSTET4 (Shelf)
  • TET4000 (Power module / supply)
  • 00210 (PDU) and ZLH.U1C00.0 (cable harness set)
  • NAC2006-01 (Controller)

The SPSTET4 System is designed for secure remote monitoring and is fully compliant to EMC and safety standards and carries the CE mark. The converter can operate in a fan cooled environment and uses digital controls for fan speed regulation.

These new SPSTET4 system products are highly efficient with excellent dynamic response to load / input changes and low output voltage noise. This includes a six-slot shelf, PDU and shelf controller for full remote control and monitoring of the system via SNMPv1/2c/3 through a 10/100 MB base ethernet port.

Shelves are available for OCP V2 bus-bar style connection. The PDU fits into the OCP V2 4kW rack opening and cables from the PDU to the shelf are available as well, making this a one-stop-shop V2 power solution.

The converters are 4kW each, hot swap capable and fully protected against over-current, -voltage, -temperature and reverse polarity. Features include active analog current share for parallel and redundant operation, as well as secure remote monitoring with the SNMPv3 protocol via the Network Attached Controller hosted in the shelf.

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