Regenerated 1-phase Electricity Meter 12EA5RN 5/60A REDS

Internally, the meter was designed for precise measurements. The current circuit utilizes an innovative four-terminal shunt, while the voltage circuit incorporates a resistive voltage divider. These components are compacted inside the meter's robust housing. Signals from the shunt and resistive divider are passed to a specialized measurement circuit based on an advanced integrated circuit. The resulting pulses to the registers, pulse output, and light-emitting diode are proportional to the amount of electrical energy flowing. Measurement data and programmable parameters are securely stored in the non-volatile EEPROM memory, ensuring reliability and continuity of measurements even in the event of a power loss. The meter's housing, made of non-flammable plastics, meets stringent tightness standards and includes provisions for affixing legalization marks, confirming its authenticity. All measurement data and parameters are clearly presented on the LCD display, which allows for easy reading even in the event of a power outage. A dual-function button, secured with a seal, makes operating the meter convenient and safe. The large nameplate provides full information about the meter, connection method, and communication interfaces, ensuring complete transparency. The meter is equipped with optical connectors and optional RS-232 and RS-485 interfaces, enabling communication with other systems. Special protective elements ensure reliable operation of the meter even under adverse voltage and current conditions in the power supply network. Additionally, the meter is designed for automatic calibration, ensuring its measurement accuracy over a longer period of time.
