IGBT power interface integrates electro-optic conversion
Harting has developed a range of miniaturised power interfaces with integrated electro-optical conversion, enabling customers to save time and money by combining electrical connectivity and optical transmission in the same module.

The new interfaces are designed for use with powerful electric drives controlled by IGBT (insulated gate bipolar Transistor) semiconductor elements. In order to achieve the necessary galvanic isolation between the controller and driver board, data is transferred via fibre-optic cable. In order to simplify the connection of POF fibres, as well as saving space on the controller board and reducing downtime during service, the electro-optical conversion process has been integrated into application-specific connectors. For traction control on trains, a solution for up to 16 optical channels is available in a DIN D20 metal housing. In harsh industrial environments, a Han 10A housing variant with IP 65/67 protection offers up to eight channels. The range is completed by a pluggable 8-channel module for direct connection to the circuit board in the switch cabinet.

In all variants, the fibres are connected by means of a metal clip which attaches them without any additional optical contact.
