| APPLICATION |
| DDS228 Single Phase Electronic Watt-Hour Meter applies to the working conditions of power electricity metering of 50Hz or 60Hz frequencieys, the 10℃~+50℃ environmental temperature and the humidity not more than 85%. |
| STRUCTUTAL FEATURES AND WORKING PRINCIPLE |
| This Electronic Single Phase Watt-Hour Meter adopts micro-electronic 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 ratio with the voltage current.Then the counter is driven by frequency dividing stepping motor to meter the power. |
