AD-LU 650 GT

Description

The AD-LU 650 GT is a digital measuring transducers for the acquisition of all measured variables in the three-phase network. In addition to the fundamental oscillations, the harmonics up to the 32nd harmonic are also measured for currents and voltages. In addition to the three phase currents, the current in the neutral conductor can also be measured. Any measured variable can be assigned to each analog output. Each digital output can be assigned its own function such as limit value monitoring or pulse output for an energy meter. All measured data can be read out via the Modbus-RTU interface. With an optional display device such as the AD-MM 400 FE or the AD-MM 500 FE, the data can be displayed and the device can be configured if necessary.

AD-LU 650 GT
