UR Group – Low power switchers with new terminal block connector option

The LP25 and LP40 series’ of low-power switchers now provides a new terminal block option. Both models, manufactured by Astec Power, feature a terminal block connection for both AC input and DC output and are available from UR Group.

The single- and triple-output models have a 3-inch x 5-inch footprint and deliver from 25W to 55W of total power, depending on the model and whether the units are convection- or forced air-cooled. Featuring universal input from 85VAC to 264VAC, all models have adjustable outputs, remote sense and built-in EMI filtering as well as over-load, over-voltage and thermal protection.

The compact footprint means that the units are well suited to a variety of low-profile applications including 1U (1.75-inch) rack installations. With their low-profile design, small footprint and flexible connection options, the low-power switchers are suitable for a variety of uses including test and measurement, single-board computers, telecommunications and networking.

With a wide operating temperature range from 0C to 50C without de-rating, the new LPS models can function at up to 70C by de-rating the output 2.5% per degree C. They 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 25C ambient conditions. They comply with international safety and performance standards including UL, CSA, NEMKO, CB and CE, as well as satisfying RoHS requirements, says the company.
