Error stability, linear good, service life period set-up not;
Temperature characteristic, working temperature range wide;
Light load performance is good, the product in the extremely low load has the very good accuracy;

DDS566 type single-phase electrical meter using large scale integrated circuit as the core device, its periphery less component, high reliability, light weight, beautiful modelling, and have a real preventing electricity-stolen, at high magnification, the overload, high precision, high stability, low power consumption, etc. Advantages, used for measuring frequency for frequency 50 Hz ac active power, is the traditional inductive watt-hour meter the upgrading of products.

The products fully meet the GB/T17215-2002 (idtIEC1036:1996) of single-phase electrical meter in all the technical requirements.
