Operation
Special electronics for under the influence of the flowing current and the applied voltage, it generates impulses in an amount proportional to the electricity consumed. Energy consumption is signaled by blinking LED. The number of pulsesóis converted into consumed energy, and its value is indicated through a segmented 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 counter from being bypassed.
