18kW HVDC-Input Power Shelf Compatible with Open Compute Racks

Bel Power Solutions and Protection has announced the SPSPFE3-07 power shelf, which provides rectification, system management and power distribution from HVDC mains (240/380Vdc) power into a main output of 12Vdc for powering intermediate bus architectures up to 15kW (5+1) in high-performance servers, routers and network switches.

Each SPSPFE3-07 shelf can be configured with up to 6X PFE3000-12-069RA or TET3000-12-069RA power supplies, which are both hot swap and redundancy capable, and contain two separate dc inputs (one inlet powers 3 power modules).

Featuring full digital controls for improved performance, cooling is managed by a fan controlled by the DSP controller. The shelf is compatible with the Open Compute rack design.

The shelf incorporates system communications via the I2C/PMBus™ protocol, allowing for full monitoring of supplies, controls and programming. Multiple protections such as overtemperature, output overvoltage and output overcurrent are also standard.

An always-on +12V 60W standby output is provided, as well as a slot for an optional Network Attached Controller, which can be included in the shelf or bought separately. The Network Attached Controller provides monitoring and control functions through a 10/100 MB base Ethernet port and can be connected directly to the data center management network.

SPSPFE-07 samples are available upon request.
