HPF-320
High-pressure fuel pump driver delivering precise current-controlled operation for motorsport applications.
The HPF-320 is a compact fuel pump driver designed for motorsport environments, providing precise control of high-pressure fuel pumps via a current-controlled waveform. Operating alongside a powertrain control unit, it uses a single trigger input with configurable parameters over CAN, enabling optimised pump performance and integrated diagnostics.
