Life Racing PDUX4B | Ultimate High-Density Intelligent PDU

The Life Racing PDUX4B is the definitive solid-state power management solution for elite-level motorsport. With a massive 48 main power outputs, this unit is designed to control every electrical component on a modern racing vehicle—from complex engine cooling and lighting arrays to sophisticated cabin systems—without a single physical fuse or relay. Featuring advanced schematic-based logic and high-speed networking, the PDUX4B provides total vehicle control with aerospace-grade reliability.

Unrivaled Power Output Density

The PDUX4B provides the most comprehensive output suite in the Life Racing lineup, featuring 48 protected main channels:

• 10 Multifunction Outputs: Highly flexible high-side, low-side, PWM, or H-Bridge drivers (40A continuous, 60A hard-start inrush).

• 10 High-Power Outputs: Dedicated 40A continuous outputs for high-load components like electric water pumps and radiator fans.

• 28 Standard High Side Outputs: 15A continuous outputs providing massive expansion for sensors, lights, and auxiliary systems.

• Intelligent Protection: Every output includes multi-stage in-rush control, thermal monitoring, and short-circuit protection.

• Output Teaming: Channels can be software-linked to drive ultra-high-current devices.

Advanced Control & Simulation

• Logic Simulation Tool: Use the visual schematic-based calibration software to build complex logic and simulate the entire electrical system before the vehicle even turns on.

• ECU Integration: Full I/O slaving support allows any of the PDU’s physical inputs to be utilized as general-purpose analogue inputs by a Life Racing ECU.

• Efficiency Management: Intelligent low-power states ensure minimal battery drain, with "wake-on-activity" via CAN, physical inputs, or a dedicated wake pin.

Elite Networking & Communication

• Dual Ethernet Switch: 2x 100Mbit/s full duplex Ethernet ports enable the PDUX4B to act as an onboard network switch for other Ethernet-enabled devices.

• Triple CAN Bus: 3x CAN 2.0B interfaces for high-speed communication with dash displays, data loggers, and PDMs.

• Peripheral Support: Integrated LIN Bus and RS232C serial interfaces ensure compatibility with a vast range of industrial and motorsport sensors.

Battle-Proven Hardware

Constructed for the most grueling endurance environments:

• Connectivity: Dual Leavyseal connectors (113 pins) and a heavy-duty Amphenol SurLok Power Stud for the main battery feed.

• Chassis: CNC machined aluminium enclosure designed for superior heat dissipation and vibration resistance.

• Versatility: Available in both 12V and 24V variants with a regulated 5V sensor supply and dedicated logic power input.

• Operating Range: Reliable performance in extreme heat up to +85°C.
