Emerson Intros Astec LPS120 Series Switching Power Supplies

August 29, 2005 by Jeff Shepard

Emerson Network Power, a business of Emerson (St. Louis, MO), announced the addition of five new models to its high-density LPS120 switching power supply family from Astec Power (Carlsbad, CA). At 6.7 W/in³, the units will deliver up to 130 W of total power with output voltages of 3.3 V, 12 V, 15 V, 24 V, and 48 V in addition to the 5 V output offered by the recently introduced LPS122 model.

Units can deliver their full-rated output of 130 W with 30 CFM forced air or 80 W with convection cooling. Featuring active power-factor correction to minimize input harmonic distortion, the LPS120 Series compact 85 Vac to 264 Vac power supplies are suitable for 1U (1.75 in) rack installations and other low-profile applications. All models also offer a 12 V, 0.5 A auxiliary output and 5 V at 0.5 A standby output, as well as overload, over-voltage, and thermal protection.

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 0 °C to 50 °C without derating, the LPS120 models can function at up to 70 °C by derating the output 2.5 percent/°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 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.
