ME631 Three-phase energy meter
Operation Manual V1.2
Three Phase Intelligent energy meter
—ME631
Summary
ME631 three-phase energy meter has many functions, for example three current, voltage, power, harmonic meter, etc. Adopting AC sampling technology, can measure three-phase current, voltage, power and harmonics of electrical meters directly. It not only can be used for local display, also can be connected with the industrial control equipment.
Typical applications
>Power monitoring: On the system of internal line and load for real-time remote monitoring
> Energy management: Satisfy the customers for electricity metering and cost allocation of special needs.
Functions and features
Convenient installation
>Both sides are equipped with two removable installation card, without using any external tools that can be flexible operation, convenient installation and modification of the scene.
>Instrument thickness is only 100mm, save the space in the cabinet.
>When the phase voltage is below 431V, it can be connected directly without extra voltage transformer etc.
Remote information and control
>The instrument with four digital inputs by itself. And control changes of interface parameters.
>Relay outputs, the coil can be connected directly to the circuit breaker, to realize the remote control function. (If you need to relay function, please explain the demand to the manufacturers).
International standard
>Power precision grade 0.5, consistent with the IEC 62053-22 that international electric metering accuracy requirements.
>The instruments meet the standard full performance of the IEC61557-12(IEC 61557-11 PMD/S/K70/0.5).
Power quality analysis
>The total harmonic distortion rate of measurement system HD, can analysis the pollution situation effectively.
