Three-phase Four-wire Electronic Watt-hour Meter(LTM34-2a)

Detailed Product Description

Product Brief Introduction
This  three-phase  electronic watt-hour meter adopts advanced microelectronics technique

and SMT manufacturing technology. Its performance conforms to IEC61036 Standard,whose

rated frequency is 50Hzor60Hz.The meter own the function of forward direction, reverse 

direction  electric quantity metering respectively or act-ive forward and reverse

direction power accumula-tion metering ,which is optional. The meter with characteristics

of LCD displaying means or stepregister 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 Feature
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. It could be display when lack of a phase.   
4. Own passive electric energy impulse output terminal, the impulse output is square

wave, and the impulse width is 80ms.
5 .adopt transparent cover, which made of self-extinguishing ABS material, and  the 

connecting  terminal made of bakelite  IP54, which designed are waterproof and dustproof.
