The VARIMETER PRO DOLD series, available from ELTRON, consists of advanced measuring modules and relays designed to monitor voltage, phases, frequency, asymmetry and the status of power supply lines in 3-phase and 1-phase installations. The devices in this series are distinguished by their compact design, high precision and reliability, which are essential in industrial, energy and building applications.
VARIMETER PRO modules enable:
The VARIMETER PRO series devices available from ELTRON also offer a test function, adjustable response delay and are available in various housing widths – from 17.5 mm for compact applications to 75 mm for extensive measurement functions.
These are ideal solutions for building automation, heavy industry, server rooms, emergency power supply systems and wherever continuous network parameter diagnostics are required.
