Original Press Release:

3 W Isolated DC-DC Converter Series Delivers 4:1 Input Range in Compact, SMT Package

CUI’s Power Group today announced the addition of a new 3 W 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.

Ideal for converting and isolating fluctuating dc voltages, the 3 W 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 1500 Vdc 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 0.1 W. Operating temperatures range from -40 up to +71°C at full load, derating to 60% load at +85°C, making the low power modules suitable for harsh environments.

The 3 W 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°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. Please contact CUI for OEM pricing.
