Power distribution solution

Box for a leaner wiring harness

In cooperation with Dieci, Wuerth Elektronik ICS has developed a power distribution box. It is equipped with a CAN splitter.

The electrical architecture of Dieci telescopic loaders used to be characterized by a complex wiring harness and multiple fuses and relay boxes. "It was a fully hard-wired solution that took up a lot of space and was difficult to install. That was no longer smart enough for us," recalled Stefano Gabrini from the Electrical Department at Dieci.

In 2014, Wuerth Elektronik ICS came up with a platform concept for customer-specific power distribution solutions just at the right time. A standard box with customer-specific printed circuit board in which high-current fuses and relays are integrated? PCB technology combined with copper bus bars for high currents? The proposal by Wuerth, a specialist in PCB-based system solutions for signal and power distributors, piqued the curiosity of Italian machine manufacturer Dieci. The idea sounded good: main distribution is separated and fused near the batteries. And the consumers close to the batteries benefit from direct switching and fuse protection.

Within a few months, a joint team from Wuerth Elektronik ICS and Dieci defined the requirements, developed the customer-specific part of the solution called Redline Power Box Hybrid, and produced the first prototypes. "The biggest challenge during development was to fit all components on the PCB and meet the budget Dieci had set for us," project manager Florian Gackel recalled the initial prototype development phase.

Wuert Elektronik ICS developed three different variants of the box for Dieci. The first one, which has already been in series production for about three years, is additionally equipped with a CAN bus splitter. Two further versions will go into series production in 2018. One of these features is an integrated Nano ICCS on which individually programmed delay times can be set to control ignition-switched loads.

The box, located close to the batteries in the engine compartment, is robust in terms of ambient temperature. The 237,5 mm x 205,5 mm x 58 mm Redline Power Box Hybrid is specified for the temperature range -40 °C to +85 °C.

The range for the fuses in the high current range (150 A to 250 A) is designed according to protection class IP20. The IP54 sealed housing part contains the circuit board, which can be equipped on an area of approx. 90 mm x 90 mm with all available ICS sockets such as mini, ATO and maxi fuses and all common relay sockets up to high-current relay sockets.
