SchP00P, SchP01P, SchP02.01P

Small digital meters SchP00P, SchP01P, SchP02.01P are intended to measure and convert the effective value of current, voltage and frequency in one-phase electrical circuits and other AC circuits into output unified DC signals and to transmit measured values through serial digital interface RS485.
The meters are single-channel and single-scale meters with designs by overall dimensions, measurement ranges, indication ranges, supply voltage, availability of interface, digital and analogue outputs, indicators colour, accuracy class, custom design.
One-phase meters can be used in three-phase electrical circuits for measurement and conversion of parameters of one phase.
The meters could be used complete with primary transducers for measurement non-electrical values if ranges of output electrical signal of primary transducers corresponds to the meters input signal ranges.
The meters are used in the energy industry and other sectors of industry for control of electrical parameters.
