Energy Meter EM Energy Meter Leading Manufacturer Protects Solar Power Safety

ENERGY METER EM Energy Meter • Today, energy costs are impacting more and more importantly on the budgeting of any economic activity. To ensure optimum energy efficiency, the only way is by measuring the energy consumption of different loads in departments, offices, and so on.For a simple house, the need is to check and prove its efficiency class by calculating and allocating the correct energy costs for heating and/or heat pump, whereas for a big building such as a hospital, a detailed energy profile of each ward or department and of each service (lifts, HVAC,heating, gas distribution system)...

TOUCH TECH display • The EM are the first energy analysers in the market to have the TOUCH TECH system, a display-integrated touch key-pad. The TOUCH TECH display makes page scrolling and programming simpler and more straightforward, avoiding all the issues related to mechanical keys. In this way the LCD area, backlit after the first touch, can display a complete set of variables and data. Compact size, extended current inputs • Thanks to their innovative measuring technique, the EM can manage a high direct current in a very compact housing, with an extended accuracy range.The nominal current...
