Emerson Network Power has expanded its widely used Astec LP25 and LP40 switching power supply families with a new terminal block connector option.

Emerson Network Power has expanded its widely used Astec LP25 and LP40 switching power supply families with a new terminal block connector option. These models from Astec Power feature a terminal block connection for both ac input and dc output. All of the single- and triple-output models have a 3-in. x 5-in. footprint and will deliver from 25 W to 55 W of total power depending on the model and whether the units are convection or forced-air cooled. Featuring universal input from 85 Vac to 264 Vac, all models have adjustable outputs, remote sense, and built-in EMI filtering. Their compact footprint makes them well suited for 1U rack installations.

With an operating temperature range from 0°C to 50°C without derating, the switchers can function up to 70°C by derating the output 2.5%/°C. They also comply with IEC EN61000-3-2 harmonic and IEC EN61000-4-X susceptibility requirements. All models have a demonstrated MTBF of over 550,000 hrs at full load in 25°C ambient conditions.

Samples of the new models are available now with prices starting at $25 in OEM quantities. The terminal block option can be ordered using a “T” suffix on the model number, for example LPS42-T.
