Electrical variables A 9903 AB / ZA 9904 AB - 1

Electrical variables • Independent, full digital acquisition of the true/effective values of an AC variable. • Measuring signals with any course of a curve are digitised with 1kHz. • Pure digital data transmission to the measuring instrument. • Acquisition of the frequency through a second measuring channel. • Connector sockets electrically isolated and overvoltageprotected. Technical Data TRMS Accuracy: Sampling rate: Frequency range: Frequency range: Meas. period/transient time: 0.5s Electrical isolation: Frequency Accuracy: Sampling rate: Meas. period/transient time: 0.5s Types (incl. touchproof connecting cable) Operating voltage: 6 … 14V through ALMEMO® device Current consumption: AC Voltage Meas. range Internal resistance When using the measuring module for the purposes of current measurement with an external shunt. the shunt must be looped into the neu- tral conductor (not into the phase). AC Current Meas. range Internal resistance Without fuse, overload condition only up to 1 minute maximum DAkkS or factory calibration KE90xx electrical for digital measuring module (see chapter Calibration certificates). DAkkS calibration meets all the requirements regarding test resources laid down in DIN EN ISO/IEC 17025. 10/2013 • We reserve the right to make technical changes.
