E-T-A PowerPlex

E-T-A PowerPlex is a comprehensive system which, according to its makers, significantly reduces the need for conventional wiring, and combines reliability and user convenience.

E-T-A PowerPlex incorporates high-end power semi-conductors with integral protective elements for switching and protecting electrical loads. The system is free of any mechanical components which would be subject to wear or be susceptible to vibration, shock and other environmental influences. Unlike other methods of electrical protection, the semi-conductors provide integral current limitation thereby ensuring that the operating current cannot exceed predetermined limits, even in the event of a short circuit. Concept E-T-A PowerPlex consists of modules positioned as required around the vessel to facilitate the connection of loads, switches and sensors. The various components communicate with each other via a CAN bus to function as a single control system despite their different locations. As each PowerPlex module has its own micro processor, the installation does not require a central controller: each unit is able to work independently. By mounting the modules as close as possible to the loads, wiring and installation cost can be kept to a minimum.

PowerPlex offers possibilities, both for the control of on-board electrical systems and to provide added functionality for the user. In addition to its normal monitoring and switching duties, E-T-A PowerPlex can be used to perform a wide range of additional functions which otherwise could be achieved only with complex and costly electronic solutions.

E-T-A PowerPlex incorporates redundant protection as a special feature - termed Four Level Protection Concept - FLPC. This concept is based upon the interdependent functioning of four types of overload protection: software-controlled overcurrent protection with current measurement, hardware-controlled safety disconnection, intrinsic protection of power transistors and thermal protective elements with manual switching function.
