Descrizione del prodotto

The RP 9812 voltage and frequency monitor from the VARIMETER NA series is used to monitor the grid when feeding energy into the public grid. User-friendly: The unit can be adjusted quickly and simply with only three rotary switches. Use the first two rotary switches to select one of the preset standards according to the country-specific requirements. The third rotary switch is used to set the mains form quickly and easily on the device. You can adjust each parameter individually with menu-guidance in case of different requirements. All measuring variables required are constantly determined by the unit. If incorrect voltage or frequency values occur, the RP 9812 disconnects the distributed power generation System securely from the mains.
