Voltage and Frequency Monitor
Contact Person: +8801325074101
The voltage and frequency monitor RP 9811 represents a solution to monitor mains supply when feeding power to a public grid that conforms with various national standards. User-friendly: The unit can be adjusted quickly and simply with only two rotary switches. Use the first rotary switch to select one of the already preset standards according to your national requirements. Use the second rotary switch to set the type of system, quickly and simply, on the unit. 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 9811 disconnects the distributed power generation system securely from the mains.
