Various current and voltage monitoring with a maximum of 12 bits. The control units are configured to not interfere with each other.
The "AXPHDY-PDU" is a device that distributes supplied power into a 28V unregulated power supply and a 5V regulated power supply. The power supply path is configured with complete dual redundancy, and the control units are designed to not interfere with each other. This allows for continued power supply to connected devices even if part or all of one control circuit fails. 【Features】 ■ UVC and overcurrent trip control functions for connected devices ■ OBC communication function via RS422/485 (Command reception & control, telemetry transmission) ■ Electrically isolated configuration between analog and digital sections ■ Electrically isolated configuration between BUS power and 5V power ■ Various current and voltage monitoring with up to 12-bit resolution *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our main product is a power supply device for ultra-small satellites. Artificial satellites flying in space cannot be retrieved and repaired if they malfunction. In other words, "a power supply failure equals the death of the satellite," which requires extremely high reliability, as failure is absolutely not permitted. We handle power supply devices used in such environments. Furthermore, our power supply devices meet JAXA's safety requirements. *As of the end of 2018. Our power supply devices have been adopted not only for the H2A rocket but also for satellites launched by SS-520 and Epsilon. They are also used for the power supply of satellites released from the International Space Station. Our power supply devices boast a track record of being installed on over ten satellites, with no failures due to power supply factors, achieving a success rate of 100%. With our proven track record and technology, we will contribute to Japan's space industry.
