Compact DC Current and Voltage Measuring Device Щ00П

Description

Digital small-sized devices ShchP00P are 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. Single-phase devices can be used in three-phase electrical networks for measurement and conversion of parameters of one phase. Advantages: unique overall dimensions 48×24×86 mm, accuracy class 0,2 or 0,5, size of indicators 9,9 mm, extended operating temperature range from -40 °?...+50 °?.

ShchP00P is included in the State Register of measuring instruments of the Russian Federation No. 64095-16. Interverification interval - 10 years.
