3 Contents Application is a micro-controller based AC transducer with 1 analogue output for measurement of RMS voltages, RMS current, phase angle or frequency on an AC-network. can be delivered pre-configured or it can be delivered un-configured for customer configuration through the PC interface. The PC configuration software allows free choice of voltage, current, phase angle or frequency measurement including configuration of the measuring range and output range without any mechanical settings or adjustments inside the transducer. The transducer holds no mechanical moving parts like potentiometers, and the calibration stability is excellent. can be configured as a normal linear transducer or with up to three slopes giving the possibility for a higher resolution in one or two ranges of the measurement. See figure below for an example of two slopes. Upper and lower output limitations can also be configured Example of dual slope For further examples, see data sheets for TAS-321DG/TAS-331DG.

The design of the transducer makes mounting of it close to similar equipment possible, however make sure that there is min. 50 mm between the top and bottom of the transducer and other equipment. The DIN rail must always be placed horizontally when several transducers are mounted on the same rail Disclaimer DEIF A/S reserves the right to change any of the contents of this document without prior notice.
