Three-phase four-wire kwh meter

Detailed Product Description

electric meter,kwh meter,digital meter

This three-phase kwh meter adopts advanced microelectronics technique and SMT manufacturing technology. Its performance conforms to IEC 61036 Standard, whose rated frequency is 50Hz or 60Hz. The meter own the function of forward direction ,reverse direction ,electric quantity metering respectively or active forward and reverse direction power accumulation metering ,which is optional. The meter with characteristics of LCD displaying means or step-register with circular type. Also owns the advantage of measuring accuracy high, the sensitivity high, the power loss low, the load width, the volume small, the weight light and so on the characteristics,The electric quantity could add optical port or RS485 and RS232 communication, which is accorded with IEC 62056-21 or IEC 1107 requirement

 

Function and Features

1.Owning forward and reverse direction metering function,besides,it can accumulate electric quantity in one same direction (optional)

2. Adopt LCD displaying,of which there are 5 integers and one decimal-place (could increase the display number)

3.If lack of phase,it could be display

4. Own passive electric energy impulse output terminal, the impulse output is square wave, and the impulse width is 80ms

5 .there are LED which proportion with the energy output in the panel for the purpose of calibration

6 .adopt transparent cover, which made of self-extinguishing ABS material, and the connecting terminal made of bakelite, IP54, which designed are waterproof and dustproof

7. High metering precision, high sensitivity, low power consumption, wide load, small volume, light weight etc
