Carlsbad, CA (PRWEB) December 05, 2012
A new 800 watt bulk front-end power supply from Emerson Network Power, a business of Emerson and the global leader in enabling Business-Critical Continuity, meets the 80 PLUS Gold standard for efficiency. The DS800SL-3 power supply has an exceptionally high efficiency of 92 percent when operating at half-load from a 230 Vac input, combined with a typical power factor in excess of 0.99.
With a high power density of 19.05 W/in3 (1.16 W/cm3) in a slim-line rack-mounting package, DS800SL-3 power supplies enable system designers to minimize space requirements in enterprise servers and similar space-constrained applications.
The new DS800SL-3 is a fully digital design; it features a built-in I2C serial bus interface and uses the industry-standard PMBus communications protocol. Developed primarily for systems employing distributed power architectures, the power supply has a wide input voltage range of 90 to 264 Vac and is rated for 800 watts output power. The main 12 Vdc payload output is programmable by plus/minus 10 percent, and can deliver up to 65.7 A continuously. An auxiliary always on 5 Vdc output, rated at 2.4 A, is also provided for powering server management circuits. Both outputs are tightly regulated, have no minimum load requirement, and offer remote sensing the 12 Vdc output can compensate for a load bus drop of up to 200 mV.
Opposite-end ac input and dc outputs facilitate fast replacement in the field, and the dc output card edge connector is compatible with the Intel
