Converters deliver 3 W continuous power

-July 08, 2017

Comprising 11 models, CUI’s PQME3 series of isolated DC/DC converters is suitable for operation in harsh environments with fluctuating voltages. These encapsulated 3 W devices offer a 4:1 input voltage range of 9 V to 36 V or 18 V to 75 V and provide a single regulated output of 3.3 V, 5 V, 9 V, 12 V, 15 V, or 24 V.

PQME3 converters operate over a temperature range of -40°C to +71°C at full load, derating to 60% load at +85°C. Useful for a variety of industrial, test and measurement, and telecommunication applications, the parts come in 14-pin surface-mount packages with dimensions of 0.76×0.71×0.40 in. (19.20×18.10×10.16 mm). For applications where energy consumption is a concern, the PQME3 series achieves efficiency of up to 84% and no-load power draw of less than 0.1 W.

The DC/DC converters feature remote on/off control, overcurrent and short-circuit protection, and input-to-output isolation of 1500 VDC. They also meet CISPR22/EN55022 Class B limits for conducted and radiated emissions. Minimum MTBF is 1,000,000 hours at +25°C ambient, calculated per MIL-HDBK-217F requirements.

Prices for the PQME3 converters start at $10.76 each in lots of 200 units.
