ME631 three-phase power meter have many function, 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.
>Power monitoring: On the system of internal lineand load for real-timeremote monitoring
>Energy management: Satisfy the customers for electricity metering and cost allocation of special needs.
>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 connecteddirectly without extra voltage transformer etc.
Remote information and control
>The instrumentwith four digital inputs by itself. And control changes of interface parameters.
>Relayoutputs, the coil can be connecteddirectly to the circuit breaker, to realize the remote control function. (If you need to relayfunction, please explain the demand to the manufacturers).
>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.
