DC To DC Converter Transducer

We are offering dc to dc converter transducer in measuring and control circuit where a direct connection of current carrying circuit is not possible, a galvanic separation is necessary to have an interference-free operation. This transducer converts input dc voltage or current into proportional load independent dc current or voltage at output with galvanic isolation between input and output. This transducer is used mainly as an amplifying and isolating element in telemetering, computer and control systems. The input signal is buffered / amplified / summated (as per the requirement) by a precision operational amp. This signal is fed to a chopper circuit, which drives an isolating transformer. The output of the transformer is synchronously rectified and filtered. The filtered output is fed to a buffer driver which can be factory set to provide various, types of load independent output proportional to the input. The input and output circuits are powered by an isolated supply derived either from an ac auxiliary transformer (for ac auxiliary supplies) or from a dc / dc power converter (for dc auxiliary supplies)
