DDS1531 Single phase static type electric energy meter

DDS meter applies to the working conditions of power electricity metering of 50hz or 60Hz frequencies, the -10 degree to +50 degrees environ mental temperatures and the humidity not more than 85% This electric meter adopts micro-electonic technology to meter the power. It gets the voltage sampling signals from the voltage divider and gets the current signals from the current divider, then gets the current& voltage signals from the multiplier and through frequency conversion, produce a counting pulse in which the frequency is in direct ration with the voltage current. Then the counter is driven by frequency dividing stepping motor to meter the power. The electric meter applies full screen and full sealing structure. It has the features of satisfactory electonmagnetic function, low self-consumption and power-conservative, high precision electricity stealing-resistance, high overload and long service time,ect. Its capability index are totally conformed to National Standard IEC521
