Description

1. General Model DFS***6A 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 *0Hz. The meter conforms to all technical requirements specified in IEC ****6. IEC*******1, and IEC*******1 2. Features &#***9; Active energy measuring, without calibration need under long-term operation. &#***9; Double measuring circuits adopted for 1 phase 3 wires power grid system. &#***9; Excellent error linearity within 5%Ib~Imax. &#***9; Long service life and high reliability due to adopting high quality components. 3.
