Energy consumption meter 3-phase LE-03d F&F
Product description
LE-03d is a static (electronic) calibrated AC three-phase direct current electricity meter.
Compliance
MID certificate 2004/22/EC
EN 50470-1/3
Operation
A special electronic circuit under the influence of the flowing current and applied voltage in each phase generates pulses in the amount proportional to the consumed electricity in that phase. Energy consumption in a phase is indicated by flashing of the corresponding LED (A, B, C). The sum of the pulses from the three phases signaled by the blinking of the LED (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 meter has a pulse output SO+ - SO-. This allows you to connect another pulse reading device (SO) generated by the meter. It is not required to connect an additional device for proper operation of the meter.
The meter has the ability to seal the covers of the input and output terminals to prevent making a bypass of the meter.
