SEP LEM012SJ 2015 V01
c) Meter version
When the meter is switched on the power, it will display the meter version for 3
seconds.
Pulse output
The pulse led on the front of the meter is pulsing when the meter is in use, 500 pulse
per kWh (2Wh/inp.). The SEP LEM012SJ rail energy meter is equipped with an pulse
output which is fully separated from the inside circuit. The generated pulses are in
proportion to the measured energy for remote reading purposes and accuracy testing.
The pulse output is a polarity dependant, passive transistor output requiring an
external voltage source for correct operation. For this external voltage source, the
voltage (Ui) should is 5-27V DC, and the maximum input current (Iimax) is 27mA DC.
To connect the impulse output, connect 5-27V DC to connector 20 (anode), and the
