Description

The ShchP72 device is designed to measure and convert the effective value of current, voltage and frequency in single-phase electrical networks and other AC circuits into output unified DC signals and transfer the measured values via serial digital interface RS485. The device can be used in three-phase electrical networks for measurement and conversion of parameters of one phase. ShchP72 is included in the State Register of Measuring Devices of the Russian Federation No. 68259-17. Interverification interval is 10 years.
