1.General Description
Static three-circuit single-phase two-wire energy meters are designed for measuring AC active energy and variable parameters. They adopt advanced large-scale integrated circuit (IC) and SMT manufacturing technology, featuring bi-directional energy measurement, wide voltage range, anti-tamper performance, high accuracy and reliability, large overload capacity, low self-consumption, compact size, and light weight. The meter is equipped with an RS485 communication port, enabling remote reading.
The meter should be installed in a suitable environment with an ambient temperature range of -25 °C to +55 °C, a relative humidity of less than 75%, and temperature limits between -40 °C and +70 °C.
The meter is manufactured in compliance with the international standards IEC 62052-11: Electricity metering equipment (AC) – General requirements, tests and test conditions, and IEC 62053-21: Static meters for active energy (classes 1 and 2).
