Cost-Effective, Efficient Power for Control Circuits

DC-DC DIN Rail Power ConverterBulletin 1606-XLD offers reliability and efficiency in a compact design.

These power supplies are rated up to 1.48 million hours mean time between failure (MTBF) and the minimum life-time is up to 160,000 hours. Efficiency figures range up to 95.1%. Furthermore, the XLD family offers a DC “OK” signal that can be used to monitor the unit’s output voltage.

Robust enough for demanding applications, these convection cooled units can operate from -25°C up to 70°C. Typically, power derating is only required above 60 °C. The XLD family is easy to mount on any standard DIN rail and features large-sized terminals for wiring. The 240 W version is only 42 mm wide, an industry leading space saving benefit of XLD.

The new 1606-XLD product family provides high efficiencies, compact sizes, and wide operational temperature ranges.
