High noise resistance performance in the digital control unit and analog control unit! For ultra-small satellites requiring 200W of power.
The "AXPHDY-PCU" is a power control device suitable for ultra-small satellites that require up to 200W of power, combining battery control and power generation control from solar panels. It features automatic MPPT control with an analog circuit configuration designed with radiation resistance in mind, and includes functions to monitor voltage, current, and temperature. Additionally, it allows for control of the PCU via RS422/485 from the On Board Computer (OBC). 【Features】 ■ Automatic power supply function via an analog timer for the radio equipment and OBC ■ Battery overcharge protection ■ UVC and overcurrent trip control functions for connected devices ■ OBC communication function via RS422/485 (command reception & control, telemetry transmission) ■ Electrically isolated configuration between the analog and digital sections *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.
