- LE-05d 3-phase energy consumption meter F&F
Energy consumption meter 3-phase LE-05d F&F
Product description
Without neutral wire (Aron system). Three-phase. 100 A current.
LE-05d is a static (electronic) calibrated electricity consumption indicator, used as a sub-meter for indicating the consumed active AC three-phase electricity in the Arona metering system.
Operation
A special electronic circuit under the influence of the flowing current and applied voltage, in each phase generates pulses in an amount proportional to the consumed electricity in that phase. Energy consumption in phases is indicated by flashing LEDs A and C. The sum of the pulses from the three phases, signaled by flashing LEDs (800 imp/kWh), is converted into energy consumed in the entire three-phase system, and its value is indicated by the segmented LCD display. The digit after the decimal indicates decimals (0.1 KWh =100 Wh).
Note:
The electricity consumption indicator has a pulse output SO+ - SO-.
Electricity consumption meters have the ability to seal the covers of the input and output terminals to prevent making a bypass of the indicator.
