PDUX3B

The PDUX3B represents the latest advancements in microprocessor-controlled power distribution systems. The PDUX range offers advanced features such as soft-starting power demanding components, Custom CAN configuration and real number (floating point) manipulation and comparison.

Regarding power saving, the PDUX range has the ability to sleep and wake via CAN bus messaging or by using hardware pins including the ability to wake/sleep upon the triggering of certain user-specified sensor inputs.

The PDUX3B comes equipped with 34 programmable outputs in total, including 10 extremely capable multifunction outputs which can be defined by the user to operate in either discreet high-side, low-side switching, high-side PWM, Half or Full bridge operation. These flexible outputs, as well as the PDU's 16 input channels and additional 4 low-side PWMs, can be used to expand and enhance the I/O configuration of any Life Racing ECU. A feature and build-time-choice option are available for an internal IMU and two-wire wheel speed interface respectively.
