the more consumption happens. The constant of the LED is 1000imp/kWh.
Reading the meter
The S DM120A e nergy m eter i s e quipped w ith a 5 +1 r egister. F ive i ntegers a re m arked w ith b lack c olor
and one d ecimal is m arked w ith red. The S DM120D s eries energy meter i s equipped w ith 6 d igits L CD
display which is used as recording consumption and can't be reset to zero. Before the accumulated
reading go to 10,000kWh, the LCD shows in xxxx.xx (4 integrals+2 decimals). After the reading
reaches to 10,000kWh, the LCD shows in xxxxx.x (5 integrals + 1 decimal). The Max. reading is
99999.9kWh.
Pulse output
The SDM120 Series DIN rail energy meter is equipped with a pulse output which is fully separated
from the inside circuit. That generates pulses in proportion to the measured energy for accuracy
testing. The pulse output is a polarity dependant, passive transistor output requiring an external
voltage s ource f or c orrect o peration. F or t his e xternal v oltage s ource, t he v oltage ( Ui) s hould i s 5 -­27V
DC, and the maximum input current (Iimax) is 27mA DC. To connect the impulse output, connect
5-­27V DC to connector 7 (anode), and the signal wire (S) to connector 6 (cathode).
