3W Isolated DC-DCs Handles 4:1 Input RangeJune 27, 2017 by Jeff Shepard
CUI's Power Group today announced the addition of a new 3W isolated dc-dc converter series to its portfolio of low power dc-dc converters. The PQME3 series housed in a compact, industry standard 14-pin surface-mount package measuring 0.76 x 0.71 x 0.40 in (19.20 x 18.10 x 10.16 mm), provides a rugged, low-power solution for a variety of industrial, test and measurement, and telecommunication applications, thanks to its encapsulated design.
Designed for converting and isolating fluctuating dc voltages, the 3W series features 4:1 input ratio ranges of 9- to 36-Vdc and 18- to 75-Vdc, single regulated outputs of 3.3-, 5-, 9-, 12-, 15-, and 24-Vdc, remote on/off control, and 1500Vdc input-to-output isolation. For devices where energy consumption is a concern, the PQME3 series offers efficiency up to 84% and no-load power draw less than 0.1W. Operating temperatures range from -40 up to +71 degrees C at full load, derating to 60% load at +85 degrees C, making the low power modules suitable for harsh environments.
The 3W isolated dc-dc converters also meet CISPR22/EN55022 Class B limits for conducted and radiated emissions, while carrying over current and short circuit protections as well as a minimum MTBF of 1,000,000 hours at +25 degrees C ambient, calculated per MIL-HDBK-217F.
The PQME3 series is available immediately with prices starting at $10.76 per unit at 200 pieces through distribution.
