Power distribution in a standard housing

Redline Power Boxes is a system solution from Wuerth Elektronik ICS: a new approach to enabling power distribution, signal transmission, and function management in commercial vehicles.

The central feature of the Redline Power Boxes series is the standardization of the housing, while at the same time maintaining the possibility to configure the circuit board entirely to the customer’s individual specifications.

The available space in the cabins of construction and agricultural vehicles is getting smaller, with the result that parts of the power management and control modules must sometimes be installed outside the cabin. This makes it necessary to provide additional protection against dust, moisture, and other environmental influences. At the Bauma 2016, Wuerth Elektronik ICS presents a correspondingly 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

The Redline Power Box Medium is a compact solution for subdistribution circuits and control systems. It enables to position the required functions decentralized in close proximity to the consumer, 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 ICCS controllers and Micro CAN modules – opens up a multitude of additional options: Local functions such as hydraulic grabs or lifting platforms can be directly controlled by a CAN network at the place of 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 realize customized solutions with only a minimum of development effort. The sealed housing (IP64 protection classes) features a circuit board measuring 85 mm x 70 mm. It can be equipped entirely according to the customer’s specifications – suitable for ICS fuse and relay bases.

The plug-in interface takes the form of a 31-pole heavy duty plug connector, featuring four high-current contacts for connecting wires with cable cross-sections of up to 6 mm² and 27 contacts with cable cross-sections of up to 2,5 mm². The pins can be configured according to the customer’s individual specifications.

The Redline Power Box Hybrid combines circuit-board technology with copper busbars for high currents. Main potentials are separated and fused in the direct vicinity of the battery. The consumer near the battery profits from the direct circuitry and fuse and different copper busbars enable individual stop alternatives. It does not allow for the integration of CAN modules.

Benefits of the platform concept

The platform concept behind the Power Boxes enables a range of applications to be realized and requirements to be met. The housing is standardized, which means that tooling costs are kept to a minimum. The individual layout and customized configuration of the circuit boards ensures a high degree of functionality. The cover of the housing can be fitted and removed without the need for extra tools. High IP protection classes guarantee a high degree of safety. Customer-specific projects – from the circuit diagram all the way to the finished product – can be realized.

The Bauma 2016 trade fair, which is being held in Munich from April 11 to 17, is the place to go to find out more about these systems. Wuerth Elektronik ICS will be exhibiting in hall 5, stand 306 to present an overview of its entire product portfolio, including the Redline Power Boxes.
