Astec Introduces 1U, High-Density, Single-Output Compact Switcher

Power-Factor-Corrected, 125-Watt LPS125 Features Standby and Auxiliary Outputs

CARLSBAD, Calif. - March 3, 2003 - Astec Power, a leading merchant supplier of power conversion solutions, has announced the introduction of its LPS125 switcher - the first model in its new high-density 3 x 5 power supply family. Weighing in at 6.7 Watts per cubic inch, it can deliver up to 130 Watts total power. Featuring active power factor correction to minimize input harmonic distortion, the LPS125 is a compact 85-264 VAC power supply that is ideal for 1U (1.75-inch) rack installations and other low-profile applications. The unit can deliver its full rated output of 130W with 30 CFM forced air or 80W with convection cooling. This compact low power switcher is ideally suited for a wide variety of applications including telecommunications, networking, test and measurement, single-board computers and gigabit Ethernet devices.

Only 1.29 inches high, the LPS125 has a compact footprint of only 3 inches by 5 inches and can be set up for lengthwise or crosswise airflow, giving designers layout flexibility. The device also features a 12V 1/2A auxiliary output and 5V at 1/2A standby output, as well as overload, over-voltage and thermal protection.

It includes a built-in Class B EMI filter, remote sense, remote inhibit and single-wire parallel on the primary output that enables current-sharing to balance loads. The new LPS125 model has an operating temperature range of zero to 50°C without derating and can function up to 70°C by derating the output 2.5 percent per degree C. It includes IEC EN61000-3-2 harmonic and IEC EN61000-4-X susceptibility compliance.

The LPS125 demonstrates a mean time between failures (MTBF) of over 550,000 hours at full load in 25°C ambient conditions. It also complies with worldwide safety and performance standards from UL, CSA, VDE, NEMKO, CB and CE.

Available now, pricing begins at $95.00 in OEM quantities. For more information, please contact an Astec power representative in your area. To locate a representative, go to the Astec Power Web site at, and click on the SALES OFFICE button on the home page.
