1 General
DDS(X)1036A Single Phase Static Watt-hour and VAr-hour meter is designed with
state-of-art integrated circuit (IC). With advantages of few components, simple construction, high reliability, low power consumption and long service life, it can
be used in measuring single phase AC active and reactive energy with 50Hz rated
frequency.

The meter conforms to all technical requirements specified in IEC 61036, IEC61268,
IEC62052-11, and IEC62053-21

2 Functions
