Operation
Special electronics for under the influence of the flowing current
and the applied voltage in each phase, it generates impulses in an amount proportional to the electricity consumed in that phase. The energy consumption in the phase is indicated by the flashing of the appropriate LED (L1, L2, L3). The sum of the pulses from the three phases, indicated by the blinking of the LED diode (800 pulses/kWh), is converted into energy consumed in the entire three-phase system, and its value is indicated by the segment LCD display. Decimal places are hundredths (.01 KWh =10Wh).
 

Attention!The indicator has a pulse output SO+ - SO-. This allows to connect another impulse device (SO) reading the impulses generated by the indicator. For the correct operation of the indicator, it is not required to connect an additional device.
The indicator has the option of sealing the covers of the terminals  inputs and outputs preventing the meter from being bypassed.
