Emerson Intros Bulk Front End Supply
Programmable 460W 1U power supply.
Carlsbad, CA — Emerson Network Power has introduced the DS460S-3 bulk front end AC-DC power supply, calling it a breakthrough in efficiency and density for applications that use distributed power architectures, such as computing, storage, networking, datacom and test and measurement systems. \par \The new power supply can achieve a high typical conversion efficiency of 92 percent at 50 percent full load, the Climate Savers Computing Gold standard. With a 1U x 2U form factor and only 7.75-in. (196.9mm) long, the unit is especially suitable for length-limited applications and mid-plane design configurations and, at a height of only 1.6-in. (40.5mm), fits neatly into 1U rack-mounts. Rated at 460W, the power supply generates a main payload output of 12VDC and an auxiliary output of 12VDC for powering standby circuitry. It accommodates a wide 90 to 264VAC input voltage range and uses 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. Digitally programmable, the new unit is equipped with an I2C interface available with industry-standard PMBus communications protocol. The DS460S-3 also features a built-in low noise "smart" fan and holds safety certifications from UL/cUL, NEMKO, CB, and CE.
