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.

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.
