The very compact design makes the energy meters ideally suited to accommodate a large number of measuring instruments in the smallest space. The small size means the meters can also be fitted in existing switch cabinets without having to install new switch cabinets. The robust design has certainly proven itself under tough industrial conditions. The design of the energy meters is specifically designed for such applications, as is shown by a high level of reliability and durability. The display shows energy, current, voltage and active output.
