VARIMETER NA - The grid under control

With its voltage and frequency monitors of the VARIMETA NA series, DOLD offers a safe and standards-conform solution for optimal grid monitoring during energy input into the public grid. The devices are used for voltage and frequency monitoring for decentralised in-house power generation systems. They are very user-friendly and can be configured with only two rotary switches. Thanks to preprogrammed parameters, DOLD voltage and frequency monitors are quickly and easily deployable depending on the respective standard or guideline.
