DDS228 single-phase electronic energy meter (Winbond meter) specifications and functions

Winbond Energy Meter Category:

1, according to the structure and working principle points: inductive watt-hour meter, electronic watt-hour meter. Electronic energy meter can be further divided into all electronic energy meter and electromechanical pulse energy meter.

2, according to the accuracy of the level of points: ordinary level: 0.2S, 0.2,0.5S, 0.5,1.0,2.0,3.0 level, for measuring electrical energy. Precision level: 0.01,0.05 level, mainly as a check-level calibration of ordinary energy meter basis.

3, divided by purpose: 1) active energy meter. 2) Reactive energy meter. 3) The maximum demand scale. 4) Rate Power Meter. 5) Multi-function energy meter. (6) According to the nature of access to power can be divided into: AC power meter and DC power meter. (7) In accordance with the meter installation wiring can be divided into direct access and indirect access (through the transformer access); which due to the different measurement circuits, usually divided into single-phase energy meter, three-phase three-wire Meter and three-phase four-wire watt-hour meter. (8) According to the average life expectancy, single-phase induction watt-hour meter is divided into: ordinary type and long-life technology watt-hour meter.

DDS228 single-phase electronic energy meter Overview:

Winbond instrument production DDS228 single-phase electronic energy meter (hereinafter referred to as energy meter) ADI's single-phase energy measurement chip ADE7755 US and advanced SMT and wave soldering process, according to the actual power consumption of the user design, manufacture new Meter.
