Two-Phase Three Wire electronic watt-hour meter(LTM23-2)

Detailed Product Description

Product Brief Introduction

This two-phase three-wire electronic watt-hour 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 .adopt transparent cover, which made of self-extinguishing ABS material,

and the connecting terminal made of bakelite, IP54, which designed are

waterproof and dustproof
