Bel Power Solutions Announces Platinum Efficiency 3600 W Power Supply for Big Data and Cloud Computing

Delivers 3600 W of Additional Power in the Standard 6-Position Shelf

Santa Clara, CA [January 17, 2019] Bel Power Solutions and Protection, a Bel group company (NASDAQ: BELFA and BELFB) and premier global manufacturer of power management devices, announces the Platinum efficiency PFE3600 series power supply, which delivers more power in a standard form factor for big data and cloud computing applications. This power supply features a compact form factor (69 x 42 x 555 mm) which converts standard AC mains power or high voltage DC bus voltages into a main output of 12 VDC.

The new PFE3600 series is designed to meet the growing power requirements of high performance servers and super computers running scalable and distributed computing of large volumes of data. Sometimes referred to as hyperscale computing, these applications include blockchain processing, artificial intelligence (AI), data analysis in scientific/medical research, cyber security and real-time consumer analytics. Many of these datacenters are following the principles of the Open Compute Project (OCP).

The PFE3600-12-069RA (reverse airflow) 3600 W is available as an AC-DC power-factor corrected (PFC) or DC-DC power supply, for the growing number of DC-powered datacenters and for powering high voltage DC (HVDC) equipment. The PFE3600-12-069RA is hotpluggable and includes parallel operation with active current sharing or analog bus and full digital controls for improved performance. An always-on +12 V 60 W standby output is provided, as well as I2C communication. The PFE3600 meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD).

The PSU can be used interchangeably with Bel’s PFE3000 to upgrade power levels in one of the company’s standard 6-position shelves, such as the Bel SPSPFE3 power shelf, which can provide a maximum power output of 21.6 kW in a single 23-inch shelf. The new power supply would provide 20 percent more power in the same rack space.

Samples of the PFE3600 are available upon request from your sales representative. The PFE3600 is available from Digi-Key, Mouser and Arrow. For more detailed information, visit the PFE3600 product page here or download the datasheet.
