Electronic Meter

* APPLICATION of Electronic Meter

DDS228 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 electric 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.
