Within the past 20 years SITAEL made several developments in the field of Electric Propulsion avionics, with a focus on High Voltage Power Supplies (HVPS) and Power and Processing Units (PPU) for Low and High Power Hall Effect Thrusters (HET). SITAEL PPUs range from 150W up to 5kW, successfully coupled with SITAEL Thrusters (HT 100, HT 400 and HT5k).

Developed for SITAEL HT100 can support Hall Effect Thruster in the 150-260W power range.

Developed for SITAEL HT400 can support Hall Effect Thruster in the 300-800W power range.

Developed for SITAEL HT5k can support Hall Effect Thruster in the 5 kW power range. Its modularity allows to supply higher power thrusters up to 20kW.
