Detailed Product Description

1. General
Model DDS1036B static single-phase watt-hour meter is designed by using special large-scale integrated circuit (IC). With advantages of few components, simple construction, high reliability, low power consumption and long service life, it is
used in measuring A.C. active energy with rated frequency 50Hz.

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

2. Features
2.1 Active energy measuring, without calibration need during long operating period.
2.2 Reverse energy counted into total energy register.
2.3 Adopting special large-scale integrated circuit and SMT technology, with advanced
process and simple construction.
2.4 Adopting newest special integrated circuit for energy measurement with digital
multiplier inside, as a result that dynamic working scope of meter is raised remarkably.
2.5 Excellent error linearity within 1%Ib~Imax.
2.6 Long service life and high reliability due to high-quality components adopted.
