Description
The digital power and energy meter AD-LU 20 GT measures all standard values of the three-phase system (active-, reactive-, apparent-power, voltage, currents, harmonics, power factor etc.) and provides this via an Ethernet interface. The measured values can be read out via Modbus-TCP protocol. In addition, these measured values are displayed on an integrated small WEB server. The device can also be parameterized via this WEB server. The AD-LU 20 GT is also equipped with an RS485 interface. This RS485 interface with Modbus-RTU protocol is mainly suitable for connecting an external display (AD-MM 400), but can also be used to read data or parameterize. The current is fed via the front-mounted through-current converters, which can measure up to 20 A directly. However, additional current transformers for larger currents can also be connected at any time. It is possible to measure symmetrical or unbalanced 4-wire networks and symmetrically loaded 3-wire networks. Due to the integrated, efficient wide-range power supply, the device operates in a large supply voltage range and does not heat up very much.
Application
Measurement and monitoring of all electrical characteristics in electrical systems. Detection of load profiles for energy management systems, e.g. ISO 50001. Recording the energy consumption of individual consumers. Monitoring of voltage quality variables, e.g. harmonics.
