ECUMaster PMU16: Advanced Power Management for Modern Motorsport
As modern race cars have evolved, the need for advanced electronic control has grown significantly. The ECUMaster PMU16 is designed to meet these demands by providing a reliable, compact, and highly capable power management solution.
Key Benefits and Features:
Efficient Power Management: The PMU16 replaces traditional fuses and relays, offering 16 high-current outputs with continuous current sensing and self-resetting capabilities. This ensures that all connected systems, from engine management to auxiliary electronics, are protected and optimally managed.
Advanced Diagnostics and Control: The PMU16 allows for continuous logging of output state, voltage, and current. This data can be transmitted via CAN bus to dash displays, keeping drivers informed of potential issues. Additionally, users can define custom logic for output control based on analog inputs or CAN data, offering unparalleled flexibility.
Simplified Wiring and Reduced Weight: By utilizing CAN bus keypads or steering wheel switches, the PMU16 drastically simplifies wiring looms, reducing both complexity and weight.
Integrated Safety Features: The PMU16 includes an inbuilt 3D accelerometer and gyroscope for logging and crash detection, as well as an “inertia switch” that can trigger safety protocols in case of an accident.
Rugged Design: Manufactured to IPC-S-815A standards and featuring an IP60-rated CNC-machined aluminum enclosure, the PMU16 is built to withstand the harshest environments. Its components are carefully selected to ensure reliable operation across a wide temperature range (-40 to 125°C).
