Front End AC-DC Power Supply Is 1,050 Watt ModelEmerson Network Power, a business of Emerson, has added a 1,050 W model to its line of bulk front end AC-DC power supplies that meet the Climate Savers Computing gold standard for efficiency—the DS1050-3. The power supply has a power density of 19 W per cubic inch and can achieve a high typical conversion efficiency of 92% at 50% full load.

Emerson Network Power's popular distributed power front-end power supplies—with individual power ratings up to 3,000 W—feature industry-leading efficiency and density in standard 1U, 2U, or 3U form factors for applications using distributed power architectures.

The Emerson Network Power DS1050-3 generates a main payload output of 12 VDC and an auxiliary output of 3.3 VDC, or 5.0 VDC as an option, for powering standby circuitry. It features a wide 90 to 264 VAC input voltage range and employs active power factor correction to minimize input harmonic current distortion and ensure compliance with the international EN61000-3-2 standard, with a power factor of 0.99 typical. To simplify incorporating the new power supply in equipment designs, it accepts the widely available IEC C14 ac input power connector.
