CisLunar Industries builds modular, software‑defined power processing units (PPUs) and ultra‑high‑voltage power supplies (UHVPS) that convert DC power from solar, nuclear, or battery sources into precise, high‑efficiency voltages for electric propulsion, on‑orbit data centers, and in‑space manufacturing. Their hardware delivers 94‑96% conversion efficiency in compact, lightweight form factors (<10 kg, <9U) and includes configurable firmware to adapt to varying bus voltages, supporting long‑duration missions for satellite manufacturers and space industrial firms.

Problem
Spacecraft and in‑orbit infrastructure require high‑efficiency, lightweight power conversion to operate electric propulsion, high‑voltage subsystems, and manufacturing equipment, but existing converters are bulky, heavy, and not adaptable to varying power sources such as solar, nuclear, or batteries.
Solution
CisLunar Industries provides modular, software‑defined power processing units (PPUs) and ultra‑high‑voltage power supplies (UHVPS) that convert DC power from diverse sources into the precise voltages and waveforms needed for electric thrusters, data centers, and in‑space manufacturing. Their units achieve 94‑96 % conversion efficiency while weighing under 10 kg and fitting within a few rack units, enabling integration on low‑mass platforms. The hardware is built for long‑duration missions (5‑10 years) and qualified for low‑Earth orbit, geostationary orbit, and terrestrial test environments. A configurable firmware layer allows customers to tailor output parameters to unregulated bus voltages, supporting rapid production scaling and reducing mission integration time. By delivering high‑performance, resilient power conversion in a compact form factor, CisLunar enables more capable and flexible space‑based operations.
Target Audience
Primary customers are satellite manufacturers, spacecraft operators, and in‑space industrial firms that need efficient electric propulsion or high‑voltage power for on‑orbit manufacturing, data processing, and communications payloads.
