Syvecs PDUX4 Power Distribution Unit

Syvecs PDUX4 Power Distribution Unit

The Syvecs PDUX4 is the most compact and cost-effective Power Distribution Unit in the Syvecs range, designed specifically for smaller projects, club-level motorsport, or as a remote expansion module for larger systems. Despite its small footprint, it provides 10 high-performance solid-state outputs with a total current capacity of 80A. Like its larger siblings, it completely replaces traditional fuses and relays, offering intelligent current monitoring and software-defined logic in a rugged, lightweight package.

The PDUX4 is particularly popular for controlling specific sub-systems—such as a dedicated fuel pump array, a cooling fan setup, or a lighting loom—while integrating seamlessly with a Syvecs ECU via CAN bus to provide real-time diagnostic feedback to the driver.

Performance and Precision Engineering

The PDUX4 brings professional-level solid-state power management to a broader range of applications without compromising on build quality.

• Compact Efficiency: The small form factor allows for installation in tight spaces, such as inside a dashboard or near a rear-mounted fuel cell.

• Smart Fusing: Each channel has a programmable trip current. If a fault occurs, the PDU can attempt to "auto-retry" the circuit, ensuring that a momentary spike doesn't end your race.

• PWM Capability: Outputs can be Pulse Width Modulated, allowing for variable speed control of pumps and fans to reduce noise and electrical load when maximum performance isn't required.

• Billet Aluminum Case: Housed in the same high-quality CNC casing as the rest of the PDU line, providing excellent heat dissipation and IP67-rated protection against the elements.

Integration and Wiring

The PDUX4 acts as an "intelligent slave" to the ECU. When connected via CAN, the ECU can monitor the current draw of every connected device, allowing for advanced datalogging of electrical health.

• Simple Configuration: Using the Syvecs PDU software, users can drag and drop logic blocks to define how outputs behave based on physical switch inputs or CAN data from the engine.

• Digital Inputs: Features 4 physical inputs that can be used for master kill switches, keypad buttons, or basic sensors.

• Direct Battery Connection: Uses high-current M6 terminals to ensure maximum voltage stability for high-draw components.
