By Rob GrayJuly 29, 2016

Bel Fuse Inc., power solution specialists and global manufacturer of premier power management devices, announced the expansion of its power shelf portfolio by including the SPSPFE3 range of power shelves. The shelves are ideal for a varied range of applications in telecom, networking and data-center processes.

High-Efficiency SPSPFE3 power shelf is capable of delivering up to 14.4 kW of output power. This shelf facilitates power supply unit replacement under live power operation while allowing for rectification, system management, and power distribution. Its flexible design curtails the installation and maintenance time, making installation easy with hot-swap insertion. The design also leverages ample scope for future expansion.

Technical Specifications of Bel Power Solutions' SPSPFE3 Power Shelves

The SPSPFE3 is a 1U high power shelf, which can be configured with up to six hot-swap capable pfe3-0xPFE3000-12-069RA AC/DC-DC power supply units. It can convert three-phase AC mains power into the main output of 12 VDC. The shelf is highly effective in powering intermediate bus architectures (IBA) in reliability servers, routers, and network switches.

All power supply units are interconnected within the high-efficiency power shelf. The PSU Modules support I2C communication interface, enabling better control, programming and monitoring with PMBus™ protocol. The I2C communication is routed thru an I2C Multiplexer (NXP PCA9547PW).
