Description

Standard-conforming mains and system protection
With the new voltage and frequency monitor RP 9811 of the VARIMETER NA family DOLD offers a safe and standard-conforming solution for optimal mains monitoring of the energy feed to the public grid. 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 several preset standards according to the national requirement. The mains system is selected quickly and simply on the unit using the second rotary switch. Done!
