Syvecs PDUX3 Power Distributor Unit (PDU)

£2,486.00 (+VAT)

Syvecs PDUX3 Power Distribution unit has been designed to replace the use of a conventional relay box. It provides multi channel solid state logic driven processing, which is fully software configurable using the Syvecs PDU Cal tool. Features include logic inputs and power outputs with validation and debounce settings. RS232 and CAN provide communication to external displays and data loggers.


The PDUX3 offers advanced features such as the ability to sleep and wake via CAN bus messaging or by using hardware input pins as triggers. It also comes equipped with an impressive 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 or low-side switching, low-side PWM, Half or Full bridge operation. These flexible outputs, as well as the PDUX3 16 input channels, can be used to increase the I/O compliment of the Syvecs S7i, S7-Plus, S8 and S12 engine management systems connected using an extremely fast slave link via Canbus.

The PDUX3 is a 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 max current capacity of 350A.
