1.Product Description
DDS series watt-hour meters are divided into mechanical and electronic types.All if its functions comply with the relative technical requirement for class 1 single phase watt hour meter in IEC62053-21. It is a long life meter with the advantage of high stability, high over load capability, low power loss and compact size.
Mechanical watt-hour meters (also known as inductive watt-hour meters) have many types and models, but their structures are basically similar. They are composed of measuring mechanism, compensation adjustment device and auxiliary components (shell, rack, end-button box, nameplate)
