50W Encapsulated Sixteenth-Brick DC-DCs for Harsh Environments
Flex Power Modules introduced the PKU-S series of dc-dc power modules for the industrial/railway and telecom sectors, to deliver rugged, highly reliable, and high-performance dc-dc solutions.
The modules are housed in the industry-standard sixteenth-brick form factor (35.3mm x 25mm x 10.4mm / 1.39in x 0.984in x 0.41in), with sealed and encapsulated packaging. This packaging ensures their reliability when exposed to moisture, dust, severe vibration, and other harsh environmental conditions.
It comes in two variants. The PKU3500S series has an input voltage range of 9V to 36V, and the PKU5500S operates from 18V to 75V. The converters can deliver up to 15A and 50W of output power and achieve up to 91% efficiency. Input-to-output isolation is 2250Vdc.
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.
