SETO Teknolog Private Limited supplies Summation Amplifier Transducer for Computer/Control Systems. SETO Teknolog Private Limited is an ISO 9001:2000 awarded company. SETO Teknolog Private Limited offers diverse types of Dc energy meter, multifunction transducer, multifunction meter, gas analyzer etc. Summation Amplifier Transducer for Computer/Control Systems converts two or more inputs of DC voltage or current into proportional load independent DC current or voltage at output with galvanic isolation between input and output. The input signals are summated by a precision operational Amplifier. This signal is fed to a chopper circuit, which drives an isolating transformer. The output of the transformer is synchronously rectified and filtered.
