Home Protection relays Capacitor bank protection AQ-C255B Capacitor bank control and monitoring device
Description
The AQ-C255B capacitor bank control and monitoring device has been specifically designed for capacitor banks. It includes the power factor controller that functions as the control unit of an automatic capacitor bank system and can control up to five (5) capacitor banks. AQ-C255B offers a modular capacitor bank control solution for applications that require a large I/O capacity. You can add up to eleven (11) I/O or communication modules into the device for extensive monitoring and control applications. The AQ-C255B capacitor bank control and monitoring device communicates using various protocols, including communication according to the IEC 61850 standard.
Highlights:
A large I/O capacity.
Power factor controller for up to five (5) capacitor banks.
A controllable color mimic with active feedback.
Power and energy measurement accuracy of up to 0.2 %.
