Sch00P, Sch01P, Sch02.01P, Sch02.00

Digital meters Sch00P, Sch01P, Sch02.01P, Sch02.00 are intended to measure and convert a value of current and voltage in one-phase electrical circuits and other DC circuits into output unified DC signals and to transmit measured values through serial digital interface RS485 (if any).

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.
The digital ammeters and voltmeters are used in the energy industry and other sectors of industry for control of electrical parameters.
The possibility for data exchange through interface RS485 (except for Sch02.00), availability of output analogue DC signals and digital outputs allow using the digital meters in automated systems of various purposes.
