Life Racing PDUx3 Power Distribution Unit

High power motorsport Power Distribution Unit (PDU). Combines a robust billet aluminium case and the very latest power driving technology with the highest efficiency in the industry.

A total of 34 output channels with a maximum continuous current capacity of 200 amps*.

Clear and Powerful Fully Graphical Logic Programming Software - Easy to read and follow with full logic simulation ability, complete operational logic schematics can be physically printed giving quick and easy reference material for engineers working on building or maintaining the vehicle wiring.

Inputs - 16 flexible input channels capable of support 0-5v, Thermistor, Bi-polar and Frequency type signals

Slave Link - enables Life Racing ECU units to directly claim access to the PDUx3's input and output channels in order to receive data from or else control those channels with ultra-low latency

Flexible outputs - of the 34 outputs there are 10 extremely flexible output drivers configurable to operate as high power high side power switching, as Half-bridge or paired into 5x Full-bridges, these 10 outputs can also be configured to operate as low-side PWM drivers.

The PDUx3's combined flexibility allows racing vehicle system designers the freedom to use these robust PDU output channels to perform high speed control tasks managed by any Life Racing ECU. Some examples of are, direct closed loop power control of electric engine coolant pumps, fuel and oil pump power, VVT position actuators (both motors and solenoids) and direct control of DBW systems.

The PDUx3 is capable of configurable soft starting of electrical loads as well as closed loop current limitation, this can be used to reduce large, short duration inrush current which can be generated when switching on large electrical loads such as high power radiator cooling fans.

Powerful Networking - 3x CAN 2.0b, 1x LIN as well as a two port Ethernet switch

Advanced Power Management - the PDUx3 can be user configured with options for simple on/off operation with the units main supply voltage. But is also capable of automatic wake/sleep operation which can be set to be triggered either by switching dedicated "wake" pin, or can be configured to wake on activation of inputs channels 13 to 16. The wake and sleep operation of the unit can also be controlled by CAN bus operation, wake on bus activity or upon receipt of a specific CAN message, all with fully user configurable address's and operational parameters as well as timeout settings for auto sleep.
