3 Product description
The AD-LU 60 FE and its variants is a measurement and display unit for front panel
mounting. It measures all values in the three-phase network with neutral conductors.
For correct measurement, the current must be detected in each phase directly or via a
current transformer. See chapter
??
. The power cables must be looped to the device
via a plug-in current transformer.
The measured values are displayed in color on a graphical TFT display and are divided
into different displays. They can be scrolled through manually or time-controlled.
There is a basic variant as a pure display device and variants with Modbus interface
and digital outputs for counting pulses or limit values.
The device parameters such as the currents of the connected current transformers can
be achieved via a menu on the device itself or via the optional RS-485 interface.
