Single-phase electricity meter MEM

Electricity meters of the MEM type are single-phase multi-tariff meters for measuring active or active and reactive energy and power in single-phase two-wire networks.

The meters correspond to European standards EN 50470-1 and EN 50470-3, as well as to international standards IEC 62052-11 and IEC 62053-21, and are designed and manufactured according to ISO 9001 standard. The active and reactive electrical power meters, in addition to the specified standards, meet the requirements of international standard IEC62053-23.

Active or active and reactive energy.

Maximum power, integration period from 1 to 60 min.

Measurement of energy in one or two directions or absolute measurement.
(+ A, + R; -A, -R; |A|, |R|), optionally by quadrants (R1, R2, R3, R4).

Internal multi-tariff registration or external management via tariff inputs/ outputs.

Internal real time counter with DST (Daylight saving enabled).
Back-up Li-Ion battery, optional super capacitor.

Time profiles for measuring data (up to 6 channels).

Measurement of phase voltage and current and power factor.

RS485 communication interface.

For single-phase two-wire networks.

Impulse output(s) (kWh or kWh + quark).

• Simplicity, speed and ease of connecting the meter to the network,
indication of correct connection.

• Self-extinguishing polycarbonate housing.

Compact design of meter according to DIN 43857.

IP54 degree of protection against penetration of moisture and dust.

• High resistance to electromagnetic interference.

Monitoring and registering of violation of meter’s work integrity (opening of the upper or lower lid, strong magnetic field action, wrong password access attempt, …).

DLMS communication protocol.

• Possibility of switching into a remote measurement and management system by installing one of the communication modules-GSM/GPRS, PLC (S-FSK, DCSK, G3), ETHERNET, Zigbee.

• A special seal for the communication module.

Indication of the working condition of the meter and the communication module.

Relay outputs for remote and local load control.

• Power monitoring and load control with integrated switch to a maximum current of 100 A.

Optical output(s): 1000 imp/kWh (kvarh)

LIST and SET buttons (the ability to seal the SET key).

LCD display with backlight.

• Tagging data by OBIS code: IEC 62056-61.

• A programmable data set and display sequence, manually and automatically.
