The PPU-200 from Space Electric Thruster Systems (SETS) is a Power Processing Unit for Thruster with an anode power supply of up to 180 W and requires a cathode current of 5 A. This PPU has a nominal voltage rating of 250 V and an efficiency of up to 91 %. It features a microcontroller-based system with an ARM core and comes with different operating modes. The PPU requires an input voltage of 22-36 V and supports CAN or RS-485 communication interfaces. It has a mass of 1.9 kg and measures 218 x 120 x 103 mm. The PPU transforms onboard voltage to power the Hall thruster and is suitable for any mission requirement, from government-class spacecraft to commercial LEO satellite constellations.
