WZE-3 F&F 3-phase energy consumption indicator
Product description
The WZE-3 is a static (electronic) calibrated three-phase direct AC power indicator.
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 a phase is indicated by flashing of the corresponding LED (L1, L2, L3). The sum of the pulses from the three phases signaled by the blinking of the LED (800imp/kWh) is converted into energy consumed in the entire three-phase system, and its value is indicated by the segmented LCD display.
The digits after the decimal point indicate hundredths parts (.01 KWh =10Wh).
Note:
The indicator has a pulse output SO+ - SO-. This allows you to connect another pulse reading device (SO) generated by the meter. For proper operation of the meter, it is not required to connect an additional device.
The indicator has the ability to seal the covers of the input and output terminals to prevent making a bypass of the counter.
