DC-DC Converters For Industrial/Railway & Telecom Applications


Enables customers to benefit from the high power density offered by it, while also offering the environmental and physical protection

Flex Power Modules introduces the PKU-S series of DC-DC power modules for the industrial/railway and telecom sectors, to provide highly reliable, high performance and rugged DC-DC solutions.

The modules 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 series achieves high levels of reliability, with mean time between failures (MTBF) of up to 8 million hours. The new modules meet safety requirements according to the latest IEC/EN/UL62368-1 standard.

Key Features

  • Input voltage range of 9 to 36V (PKU3500S series).
  • Input voltage range of 18 to 75V (PKU5500S series).
  • 15A current provided.
  • 50W of output power.
  • Achieve up to 91% efficiency.
  • Input-to-output isolation is 2250VDC.


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