New series of low power switchers

UR Group has introduced the LP25 and LP40 series of low power switchers from its partner Astec Power, providing a new terminal block option. Both models feature a terminal block connection for both AC input and DC output. All of the single- and triple-output models have a 3 x 5-inch footprint and deliver from 25 to 55W of total power, depending on the model and whether the units are convection- or forced air-cooled.

Featuring universal input from 85 to 264VAC, all models have adjustable outputs, remote sense and built-in EMI filtering as well as overload, over-voltage and thermal protection.

The compact, 3 x 5-inch footprint of both the LP25 and LP40 means that they 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, these 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.

Samples of the new models are available now.

The terminal block option can be ordered using a 'T' suffix on the model number, for example LPS42-T.
