Product Overview:

The WattDot™Software-Defined Power Management and Distribution (SD-PMAD) is intended for CubeSat applications. It interfaces a battery, five solar arrays, avionics, and payloads into a single unified spacecraft power system. The unit offers high efficiency, radiation tolerance, and flexible power output (feedback-controlled, 5-25V) for dynamic mission requirements, enabling rapid prototyping and easy adjustments during Assembly, Integration, and Test (AIT) and in-flight operations. This adaptability makes the SD-PMAD an essential component in increasingly complex satellites.
