Multifunctional measuring relays

VARIMETER PRO - Universal measuring relays - one device, multiple functions

The multifunctional measuring relays that make up the DOLD VARIMETER PRO series offer a wide range of functionality with a minimal width. These universal devices can be installed in a space-saving manner in control cabinets and are cost-effective due to their flexible usage. With a reliable and continuous monitoring of three phase networks, the multifunctional measuring relays guarantee a trouble-free and thus efficient operation of machines and systems. Their use is also rewarding in single phase networks. The user-friendly device configuration allows an optimal adaptation to the application.
