The PDU-32 is a multi-channel solid state power stich with full microprocessor control, providing intelligent supply switch, monitoring and fusing functions for 12V and 24V common ground systems. Calibration of output activation is fully schematic. Flash, latch and logic components can be used in any combination. The validated and debounced state of all hard and soft (CAN) inputs is available to the schematic along with the trip states of outputs to allow automatic backup functions to be implemented. All input and output states and currents provided on RS”£” and CAN data streams for connection to logging or telemetry systems.
All this hardware is packaged within a lightweight CNC billet aluminium case. Designed to be installed in the harshest of motorsport environments.
