AD-LU 610 GT


The digital power measuring transducer AD-LU 610 GT measures all quantities of the three-phase network (current, voltage, energy, harmonics, phase angle, active power, reactive power, apparent power etc.) and converts these measuring values onto two freely scalable analogue outputs (20 mA / 10 V). With the integral relay, the switching of limiting values or the output of energy pulses is possible. For output of more frequent energy pulses, the AD-LU 610 GT is alternatively also available with transistor output. The unit is therefore optimal suitable for integration in energy management systems. 3- or 4-wire systems can be measured.The AD-LU 610 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 610 GT can be read out and parameterised via the integral RS485-interface with the aid of the available AD-Studio. A 96x96 mm TFT display module can also be connected to this interface. The LEDs at the front signals the operating condition, the RS485-data and the relay-status. The compact type of construction and the high performance ability with simultaneous low energy consumption allows usage in almost any application.
