Detailed Product Description

1.   General

Model MEP01-CE1 static single-phase watt-hour meter is designed by using special large-scale integrated circuit (IC). With advantages of few components, simple construction, high reliability, low power consumption and long service life, it is used in measuring single phase AC active energy consumption.

The meter can be installed indoors or outdoors in the meter enclosure with environmental temperature - 30°C ∼ + 60°C and average relative humidity less than 75%. The meter conforms to the requirements specified in IEC 61036.

2    Features and Functions

2.1 Positive and negative active energy measurement (negative energy can be counted into positive energy)

2.2  Accurate active energy measurement without any calibration during long working period

2.3 Newest special integrated circuit adopted for energy measurement with digital multiplier inside, as a result that dynamic working scope of meter is raised remarkably

2.4  Excellent error linearity within 5%Ib~Imax

2.5  Long service life and high reliability due to high quality components adopted

2.6    Broad working temperature range:-30~+60

2.7 Excellent anti-tamper performance: by adopting anti-magnetism, anti-reverse counter and special circuit design
