Bel Power Solutions Announces SPSPFE3 Series 18kW Power Shelves Compatible with Open Compute Rack Designs

Santa Clara, CA [August 15, 2018] Bel Power Solutions and Protection, a Bel group company (NASDAQ: BELFA and BELFB) and premier global manufacturer of power management devices, announces the SPSPFE3-05G and SPSPFE3-06G power shelves, which provide rectification, system management and power distribution from 3-phase AC (3W+N+PE) power into a main output of 12 VDC for powering intermediate bus architectures up to 15 kW (5+1) high performance servers, routers and network switches.

Each SPSPFE3 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 3-phase AC 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 with single or triple output bus bar (SPSPFE3-05G triple; SPSPFE3-06G single).

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 +12 V 60 W 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.
