Don't waste energy trying to monitor your electricity use when this meter from Siemens can do it for you. The meter's capable of measuring both active and reactive power. So, it can measure the energy you're consuming and the electricity that bounces back and forth between devices such as transformers, solenoids and induction motors. This makes it suitable for building management, manufacturing plants and renewable energy applications. The LCD display means you can instantly see what's going on, while the Ethernet connection with Modbus communication protocol means you can send this data to your computer, helping you to streamline your system.

• TRMS measurement method to give you precise readings
• Measuring range between 46 and 400V AC means it works with low and medium power devices
• Screw terminals for a secure wire connection

No, this energy meter is self powered. As it draws energy from the metering voltage, there's no need to fit an additional electricity supply. This makes DIN rail mounting a doddle to do.
