SchV02.1, SchV72.1, SchV96.1, SchV120.1

SchV02.1, SchV72.1, SchV96.1, SchV120.1 meters are intended to measure and convert active, reactive and total power of one-phase AC circuits into output unified DC signals and serial digital interface RS485, which allow using the meters in automated systems of various purposes.
The meters provide the possibility for programming with built-in buttons or through the interface: indication range, decimal point position; level of the controlled values of input signals (settings); change in brightness of digital indicators illumination; interface parameters.
