AQ-V211 Voltage protection IED

The AQ-V211 offers a modular voltage protection solution for substations. Voltage and frequency protection with up to five optional I/O or communication cards and powerful logic programming possibility make AQ-V211 optimal for demanding load shedding or automatic transfer applications. The AQ-V211 communicates using various protocols including IEC 61850 substation communication standard.
