Single-Phase Two wire electronic watt-hour meter(LTM12-2a)

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
