Electric energy meter. Two tariffs. Current 100A.
LE-04d is a static (electronic), calibrated indicator of electric power of three-phase alternating current in direct system. The indicator is suitable for use with an external control timer and is designed for measuring and billing in two-tariff system.
Functioning
Special electronic system, under the influence of current flow and applied voltage, generates pulses in each phase in proportion to the electricity consumed in this phase. Energy consumption in phases is indicated by flashing LED A and C. The sum of the pulses of the three phases is indicated by flashing LED (800 pulses/kWh) and is converted to energy consumed in the entire three-phase system, and its value is displayed by segment LCD display.
The number after the decimal is tenths (0.11 kWh = 110 Wh).
Indicator is suitable for registering the value of electricity in two-tariff system. Two separate displays T0 and T1 indicate the value of electricity consumption in a given tariff. Switching between the tariffs takes place when the control voltage is applied on the D input of the meter (terminals 10-11). This can done with external control clock. The T0 meter reads the value of energy consumption in the absence of control voltage at the input D. The T1 meter reads the value of energy from the appearance of the control voltage at the input D, until its disappearance. Operation of the given meter is indicated by appropriate LED.
