LP-CDU DC Signal Converter & Isolator

LP-CDU DC Signal Converter & Isolator

The LP-CDU converts a unipolar or biploar(+/-) dc voltage or current input into a proportional unipolar or bipolar dc output signal.
It's fast linear response makes it suitable for applications involving control loops and the recording of transient phenomena.
There is galvanic isolation between the input, output and the auxiliary supply.

A special version of the LP-CDU can be supplied with a Hall effect sensor (DC current transformer) to enable dc currents to be measured without using a shunt, LP-CDU-BP-HALL.
