The UG 9443 mains frequency monitor from the VARIMETER PRO series monitors the mains frequency 1-phase and 3-phase AC grids. The device is ideal for applications in which a stable mains frequency is crucial for the reliable operation of machines, systems or supply networks – for example in energy distribution, industrial plants or in renewable energy generation. The mains frequency relay continuously monitors the mains frequency and reacts reliably to deviations from the set target value. Overfrequency and underfrequency can be conveniently set so that the device can be flexibly adapted to the respective requirements. The mains frequency monitor is easy to parameterize, monitor and diagnose via a Modbus RTU interface. Early detection of impending failures and preventive maintenance Prevent costly damage and, as s user, you benefit from the operational reliability and high availability of your system.
