PPS mk1

The PPS mk1 is an autonomous power distribution unit developed by Kayser Italia, designed to convert and distribute 28 Vdc to various subsystems and payloads within a spacecraft. It is explicitly space-qualified and engineered for demanding space environments, integrating high-efficiency conversion, protection logics, and monitoring capabilities within compact and robust architectures. Each unit is tailored to mission-specific requirements, ensuring operational continuity and long-term reliability. Kayser’s Power Distribution Units (PDUs) are developed to manage, protect, and distribute electrical power across complex spacecraft architectures, designed for mission-critical environments. They integrate conversion, monitoring, and protection functions within robust, space-qualified systems, ensuring controlled energy delivery and supporting operational continuity and redundancy throughout the mission lifecycle. The PPS mk1 is part of a family of PDUs and DC/DC converters offered by Kayser Space, all optimized for radiation tolerance, thermal stability, and wide input ranges, ensuring clean, regulated, and protected power delivery. Carefully selected topologies and isolated architectures guarantee consistent performance in LEO, Deep Space, and planetary missions. These converters are engineered to support critical scientific instruments and control systems with high efficiency and robust protection, from instrument control electronics to propulsion subsystems, through optimized architectures and space-grade components tailored to demanding environments.
