1. General
Model DFS1036A single-phase three-wire static 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 may be used in measuring single phase AC active energy with rated frequency
of 60Hz.

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

2. Features
● Active energy measuring, without calibration need under long-term operation.
● Double measuring circuits adopted for 1 phase 3 wires power grid system.
● Excellent error linearity within 5%Ib~Imax.
● Long service life and high reliability due to adopting high quality components.
