Product Description

DDS**9 ARE 2.0 electronic single phase watt-hour meters. They apply to the working condition of power electricity of *0Hz or *0Hz frequency,the**0&#****4;**0v&#***1; environmental temperature and the humidity not more than *5%. This meter applies micro-electronic tec hnology to meter the power.It gets voltage sampling signals from the divider. The current divider will get the current & voltage signals from multiplier and through frequency conversion, produce a counting pulse in which the frequency is in direct ratio with the voltage current. Then the counter is driven by frequency dividing steping motor to meter the power.
