Configurable, modular power/comms blocks for in-vehicle apps

Würth Elektronik ICS has introduced the REDline Power Boxes product line. Supporting user-configuration within a standard housing this is, the company says, an entirely new approach to enabling power distribution, signal transmission, and function management in commercial vehicles.

The central feature of REDline Power Boxes is the standardisation of the housing, while at the same time retaining the possibility to configure the circuit board entirely to the designer’s individual specifications.


The available space in the cabins of construction and agricultural vehicles is reducing, with the result that parts of the power management and control modules must often be installed outside the cabin. This makes it necessary to provide additional protection against dust, moisture, and other weather effects. Würth Elektronik ICS is now presenting a protected housing package in two application-specific versions. As part of the “REDline Power Boxes” product platform, the company is launching the REDline Power Box Medium and the REDline Power Box Hybrid


The REDline Power Box Medium is a compact solution for subdistribution circuits and control systems, allowing positioning of the required functions in decentralised fashion and in close proximity to the served fucntion, thus reducing not only the dimensions of the central electrical system, but also the complexity of the wiring harness. The integration of control components – for example the ICCS controllers and Micro CAN modules – opens up a multitude of additional options. Local functions such as hydraulic grabs or lifting platforms can now be directly controlled by a CAN bus at the place of the installation, thus reducing the number of necessary connections in the on-board power supply.

Standardized components are connected with variable configuration options for the circuit boards, making it easy to realise customised solutions with only a minimum of development effort.

• The sealed housing (IP64 protection classes) features a circuit board measuring 85 x 70mm that can be equipped entirely according to the customer’s specifications – suitable for all standard ICS fuse and relay bases.

• The plug-in interface takes the form of a 31-pole HeavyDuty plug connector, featuring four high-current contacts for connecting wires with cable cross-sections of up to 6mm² and 27 contacts
