Overview-

D3MFT1 is a Multi function Power Line Transducer for simultaneous measurement of various electrical parameters of 3 Phase 3 Wire or 4 Wire electric power system. The information is available through RS 485, Half Duplex Serial Communication Port over MODBUS RTU Protocol. Use of latest circuit techniques and quality components ensures reliable operation over long periods. The Transducer are widely used in application areas where accurate and reliable monitoring of power line parameters is essential

Features:

Monitoring of various electrical parameters from a Single Transducer Replaces Multiple Analog Transducers.
Programmable CT and PT Ratio.
Modbus RTU Communication Protocol.
Complete galvanic isolation between Input, Output, Auxiliary Supply.
High long term stability.
DIN Rail, Panel Wall Mounting.

The isolator with fast response time (10 mSec) are typically used in feedback control system.

In input dc current is chopped by the chopper to convert it into high frequency ac signal. This signal is fed to an isolating high frequency transformer. The ac output current from the transformer is rectified and filtered to obtain load independent dc output current. As the transformation ratio is 1:1 the output current is identical in value to the dc input current.
