Astec LPS120 Series Models Provide 130 Watts with Single Outputs from 3.3V to 48V Featuring Current-Sharing, PFC and Built-In EMI Filtering
August 30, 2005 (Press Release) --
CARLSBAD, Calif. — August 30, 2005 — Emerson Network Power, a business of Emerson (NYSE:EMR), has announced the addition of five new models to the popular high-density 3 x 5 LPS120 switching power supply family from Astec Power (www.astecpower.com). At 6.7 Watts per cubic inch, the units will deliver up to 130 Watts of total power with output voltages of 3.3V, 12V, 15V, 24V and 48V in addition to the 5V output offered by the recently introduced LPS122 model. Units can deliver their full rated output of 130W with 30 CFM forced air or 80W with convection cooling. Featuring active power factor correction to minimize input harmonic distortion, the LPS120 Series compact 85-264 VAC power supplies are ideal for 1U (1.75-inch) rack installations and other low-profile applications. All models also offer a 12V 1/2A auxiliary output and 5V at 1/2A standby output, as well as overload, over-voltage and thermal protection.
“These compact low-power switchers are a great solution for a wide range of uses including telecommunications, networking, test and measurement, single-board computers and gigabit Ethernet devices,” noted Astec Power product line manager Tom Tillman. “At only 1.29 inches high, they have a compact footprint of only 3 inches by 5 inches and can be set up for lengthwise or crosswise airflow to give designers layout flexibility that’s especially useful in high-density rack installations,” he added.
The new units include built-in Class B EMI filtering, remote sense, remote inhibit and single-wire parallel on the primary output that enables current-sharing to balance loads. With a wide operating temperature range from zero to 50°C without derating, LPS120 models can function up to 70°C by derating the output 2.5 percent per degree C. The also comply with IEC EN61000-3-2 harmonic and IEC EN61000-4-X susceptibility requirements. All models have a demonstrated mean time between failures (MTBF) of over 550,000 hours at full load in 25°C ambient conditions. They comply with international safety and performance standards including those from UL, CSA, AUSTEL, NEMKO, CB and CE.
Samples of the new models are available now with prices starting at $95.00 in OEM quantities. For more information, please contact an Astec Power representative in your area.
