Voltage and frequency monitor
Voltage and frequency monitors are a safe and standard-compliant solution for optimal grid monitoring when feeding energy into the public grid. The units can be set quickly and easily in a user-friendly manner. In case of deviating requirements, the individual parameters can be adjusted individually and menu-controlled. All required measured variables are continuously determined by the units. In the event of impermissible voltage and frequency values, the voltage and frequency monitor safely disconnects the self-generation system from the grid.
