Main structure and working principle

The electric energy consumed by the user is taken by the signal on the divider and sampled,then it is sent to the amplifier and multiplier circuit. The product signal is integrated and transformed by V/F, and output by the logical frequency division circuit to drive the LCD display to measure the electric energy.

Option

This series has two modes of cumulative counting and manual resetting, which can be elected by users according to their needs. When manual resetting, insulation rods with ameter less than 2.5 can be used for pressing the button in the reset port.This series has backlit display and normal display two options.

Installation and wiring

This product shall be connected according to the printing "L in -in" and "L out- N out" ,2.54 socket end for pulse out for error detection or as pulse signal interface.

Special Note: Due to current,voltage signal using shunt,partial voltage resistancesampling, forward and reverse accumulative count.Therefore, every meter can be top in bottom out or viceversa.
