Electric energy meter,
3-phase
Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collec� on, as well as to store the occasion of
the purchase of new equipment (in accordance with the principle of old-for-new, regard-
less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the
environment and human health.
Purpose
The LE-03M CT is a static (electronic) calibrated electricity meter
of three-phase alternating current in a semi-direct system.
Indicator is designed to work with current transformers for pri-
mary current Ip from 5÷6000 A and secondary current 5 A. The
maximum current measured value of the system is determined
by the primary current Ip applied CT (current transformer).
The user has the ability to set the index value used gear ratio,
which allows you to indicate the actual value taken by the elec-
tricity system.
Serial RS-485 and implemented Modbus RTU communication
protocol allows the indicator used in networks for remote re-
ading of data.

  • Page 1 Electro thrown in the trash or abandoned in nature, pose a threat to the environment and human health. Purpose The LE-03M CT is a static (electronic) calibrated electricity meter of three-phase alternating current in a semi-direct system. Indicator is designed to work with current transformers for pri- mary current Ip from 5÷6000 A and secondary current 5 A.
  • Page 2: Measured Values

    Functioning A special electronic system under the influence of current flow and applied voltage in each phase generates pulses in propor- tion to the electricity consumed in this phase. Phase energy consumption is indicated by flashing the corre- sponding LED (L1, L2, L3). The sum of the three phases of pulses indicated by a flashing LED is converted to energy taken in the entire three-phase system, and its value is determined by the segment LCD display.
  • Page 3: Pulse Output

    Pulse output The meter is equipped with pulse output open collector (OC type). This allows you to connect another pulse device (SO) that reads pulses generated by the meter. No additional connected equipment is required for proper ope- ration of the meter. Constant pulse counter is 12000 pulses/kWh for maximum input current meter, or the secondary current transformer (5 A).
  • Page 4 Meter number The meter is marked with individual serial number allowing its unambiguous identification. The marking is laser engraved and cannot be removed). Sealing The meter has sealable input and output terminal covers to pre- vent any attempts to bypass the meter. - 4 - - 4 -...
