▷Product Overview
The energy meter adopts the advanced LSI ADE7755, with high accuracy, Good l inearity, wide working voltage range and high rel iabi l ity, low power
consumption, wide load etc. Suitable for rated voltage 220V, rated frequency
50Hz(Optional 60Hz) Measure single phase active energy of AC.
It is complying with the requirement of single phase energy meter of
IEC62053-21, IEC62052-11 Standard.

▷Features
●The energy meter adopts advanced SMT technology and large scale integrated
circuit. Simple circuit of outside. Less components, high rel iabi l ity, no need to
adjust after long time use. Using manganese copper shut to sample on current
circuit(High precision current transformer). Not only reduce the power
consumption, but also improve the overload. The actual overload capacity of
the energy meter is more than 6 times of basic current. Simple structure,
convenient instal lation, And also it has creeping logic design.
