Single-phase two wire electronic watt-hour meter(LTM12-2)

Detailed Product Description

Product Brief Introduction

Single-phase Electronic Watt-hour Meter adopt exclusive use

LSI, The device typifying few periphery component, simple

structure, high reliability, low power consumption, long life

etc, is suitable for the single-phase AC active electric energy

with rated frequency of 50 Hz. The performance is in conformity

with the technical requirements for single-phase Electronic

Watt-hour Meter stipulated in IEC61036 Standard.

Function and Feature

1. Measure active electric energy, Do not need calibrate for

long-term operation
2. Adopt dedication meterage chip ADE7755
3. Adopting latest electricity dedication integrated circuit

including digital multiplier overseas, Greatly improved dynamic

working range of Meter , Making 10 multiple actual overload
4. Have good mistake linearity in the range of 5%Ib~Imax
5. Few periphery component, simple structure,low power

consumption
6. Adopting high reliability and long life electronic

component, So the Meter assume feature of high reliability and

long life
