AD-LU 680 GA
Description
The AD-LU 680 GA is a programmable transmitter for measuring all parameters such as power, voltage, current or frequency in the mains. The currents are registered via external clamp-on current transformer. Any measured quantity can be allocated to each analogue outlet. The measuring ranges can be configured in wide ranges. Filters, which can be individually parameterized, supplement the adaption possibilities of the measuring task. Each switching output can be assigned to a specific function. Possible functions include, for example, Limit or pulse output for energy metering.
Application
Measurement and analog output of up to 4 signals in a three-phase mains. Easy recording of currents by external clamp-on current transformer CT. Limit indicators for monitoring of up to 2 signals in a three-phase mains. Analogue front-end for energy management systems. Registration of all relevant measuring quantities of the three-phase current network and supply of the measuring quantities via a modbus interface.
Specific characteristics
- Measuring quantities: effective power, reactive power, apparent power, currents and voltages, frequency, power factor, energy metering
- The currents are registered via external clamp-on current transformer.
- Four bipolar analogue outputs as current output or voltage output, configurable per software
- Two switching outputs as relay or opto-coupler. Functions: limiting value, window, trend, S0, monitor
- Meter for effective energy, reactive energy and apparent energy
- Values for each phase and they can be polled as sum
- Output of up to four measuring quantities of the three-phase current network such as effective power, current, voltage or frequency
- Indication of the power fed back into the network is possible via analogue output and/or switching output
- Connection configurations: single-phase, three-phase current with/without neutral conductor, equally/unequally loaded
- All measuring quantities can be read out via modbus
- All measuring ranges, output ranges and device functions can be configured per software with a PC programme.
