Digital panelboard device for measurement of alternating current, voltage and frequency ShchK120.

The device ShchK120 is designed to measure the effective value of current, voltage and frequency in single-phase and three-phase electrical networks of alternating current. The possibility of information exchange via RS485 interface (Modbus RTU protocol) and availability of output unified DC signals allow to use the device in automated systems of various purposes. The instrument is a multi-channel multi-dimension and has versions by input signals, measuring ranges, number of channels, power supply voltage, interface, discrete and analogue outputs, colour of indicators, accuracy class. The device additionally has the ability to program the range of readings (device with nominal currents of channels 1 A, 5 A and voltage 100 V) and the level of controlled values of input signals (setpoints), operational change of brightness of digital indicators. The ShchK120 is included in the State Register of Measuring Devices of the Russian Federation No. 42450-11. Interverification interval - 3 years.
