AQ-F213A Feeder Protection IED

The AQ-F213 IED provides optimal performance for medium-voltage (main) or high-voltage (back-up) protection, control and monitoring applications. AQ-F213 integrates protection, control, monitoring, measuring, communication and extensive diagnostics information in one compact package. Its fully modular hardware construction gives the unit a high level of flexibility; additional I/O or communication cards can simply be plugged in according to application needs.

AQ-F213 is developed using the latest available technologies which provides protection engineers with more options and a completely new dimension to protection. The maximum usability of the IED is guaranteed by its many features, such as the graphical interface, the highly customizable HMI, the storage of PDF and other supportive documents as well as extensive user log information. Additionally, the powerful conguration and setting software tools are easy to configure and free of charge.
