Flex encapsulated sixteenth-brick DC-DC converters for industrial and railway designs
Flex Power Modules has launched two ranges of encapsulated DC-DC converters for industrial, railway and telecom designs needing up to 50W.

The PKU-S DC-DC converters are housed in the industry-standard sixteenth-brick form factor (35.3 x 25 x 10.4mm / 1.39 x 0.984 x 0.41 in), with sealed and encapsulated packaging. This ensures their reliability when exposed to dust, moisture, severe vibration and other harsh environmental conditions.

The PKU3500S series of DC-DC converters has an input voltage range of 9 to 36V, and the PKU5500S operates from 18 to 75V. The DC-DC converters can deliver up to 15A and 50W of output power and achieve up to 91% efficiency. Input-to-output isolation is 2250VDC. The mean time between failures (MTBF) is up to 8 million hours and the modules meet safety requirements according to the latest IEC/EN/UL62368-1 standard.

“Further strengthening our product offering for harsh environments such as those found in the industrial/railway and telecoms sectors, the PKU-S family enables our customers to benefit from the high power density offered by the sixteenth-brick footprint, while also offering the environmental and physical protection of these encapsulated versions,” said Olle Hellgren, Director of Product Management and Business Development at Flex Power Modules.

The PKU3000S and PKU5000S families are available now for sampling and volume production requirements.
