Description

Model DDSJ***6A 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 may be used in measuring single phase AC active energy with rated frequency of *0/*0Hz. The meter conforms to all technical requirements specified in IEC ****6, IEC*******1, and IEC*******1 1. Features ● Active energy measuring, Reversed energy counted into total energy register. ● Operating current, voltage display by LCD ● long-term operation without calibration need ● Load limitation and tamper protection with relay control off. ● Events record; ● Long service life and high reliability due to adopting high quality components. ● Parameter setting and data reading by using HHU via RS**2 port 2.
