Product description
A
DIN Rail WiFi Prepaid Electric Energy Meter is an advanced electricity meter designed to accurately measure and monitor electrical energy consumption in industrial and commercial settings. The product parameters you provided are as follows:
Related Voltage:
This energy meter is compatible with two different voltage configurations:
3-phase: 110/190V AC
3-phase: 230/400V AC
Rate Current (Ib):
The rate current, or Ib, is 5A. This means the meter is designed to handle a maximum current of 5 amperes in the circuit it is monitoring.
Communication:
The energy meter utilizes Modbus communication protocol, which allows for data transmission and remote monitoring of energy consumption.
Connect:
This energy meter connects to an AC (alternating current) power source, making it suitable for use in AC electrical systems.
Measure Type:
The meter operates in a 1-phase 2-wire (1p2w) measurement configuration, which is commonly used in single-phase electrical systems.
Pulse Constant:
The meter has a pulse constant of 1000 Imp/KWh. This parameter defines the number of pulses generated by the meter for every kilowatt-hour (KWh) of electrical energy consumed. This is useful for recording energy consumption accurately.
Operating Temperature:
The energy meter is designed to operate within a temperature range of -25 to +55 degrees Celsius (-25°C to +55°C). This wide operating temperature range ensures that the meter can function reliably in various environmental conditions.
Harmonics Emissions:
The meter complies with the IEC 61000-3-2 standard for harmonics emissions. This means it meets the requirements for limiting harmonic distortion in the electrical system, ensuring that the meter does not introduce interference or distortion in the power supply.
Overall, this DIN Rail WiFi Prepaid Electric Energy Meter is a versatile and reliable device for monitoring energy consumption in 3-phase electrical systems. It offers accurate measurement, remote communication capabilities via Modbus, and is suitable for use in various industrial and commercial applications while adhering to international standards for harmonics emissions.
