AD-LU 10 GT

Description

The digital power measuring transducer AD-LU 10 GT measures all quantities of the power-network (current, voltage, energy, harmonics, phase angle, active power, reactive power, apparent power … ) and converts these measuring values onto one freely scalable analogue output (20 mA). In addition, the device also has a transistor output for S0 pulses or for reporting limit values. The unit is therefore optimal suitable for integration in energy management systems. One phase ore balanced 3- or 4-wire systems can be measured. The AD-LU 10 GT is supplied via its measuring voltage L1. The current measuring is carried out via the bar-type transformer mounted on the front. For measuring of high voltages or high currents, external transformers can be connected in series at any time. The AD-LU 10 GT can be read out and parameterised via the integral interface with the aid of the available AD-Studio. An LED at the front signals the operating condition. The compact type of construction and the high performance ability with simultaneous low energy consumption allows usage in almost any application.
