Ecumaster PMU16 Autosport Version

The Ecumaster PMU16 Autosport Version is engineered for demanding motorsport and OEM applications where reliability and robustness are paramount. Featuring premium Autosport connectors, this unit meets the highest standards for professional motorsport and aerospace industries. The battery connection utilizes a Radlok connector rated to 200A, enabling tool-free disconnection. Output is managed via a custom 18-pin, 12AWG connector designed specifically for Ecumaster. The enclosure is CNC machined aluminium with an IP65 rating, ensuring operation in harsh, dusty, or wet environments. Compared to the standard PMU16, this version adds 6 low side outputs (2A/channel), while 14 main outputs are rated at 25A and two at 40A. Mating connectors and terminals are included.
