TAS-331DG is a micro-controller based AC transducer with 1 analogue output for measurement of power or reactive power on an AC network. TAS-331DG can be delivered pre-configured to the desired measuring val- ue and range or it can be delivered un-configured for customer configuration through the PC interface.

Features:

● Measures power or reactive power
on 3-phase AC networks
● Class 0.5 (IEC-688) measurement
● Supply and measuring voltage up to
690 V
● Easy configuration via PC interface
● Non-linear output characteristics
