Electricity meter 1-phase EX18 | 220V 10-60A | PLC modem

EX18 single-phase 220 V, 10–60 A electricity meter with integrated PLC modem

⚡ The EX18 is a multifunction electronic meter designed to measure active electrical energy in a 220 V single-phase network.

Its 10–60 A current range makes it suitable for apartments, private houses, small shops, offices and other single-phase installations.

📡 Integrated PLC modem

The principal feature of the EX18 is its integrated PLC modem. PLC means Power Line Communication — data transmission through the existing electrical power wiring.

The meter can send readings over the same cables that supply electricity to the site, reducing the need for a separate communication line to each meter.

• the meter measures electricity consumption;
• the PLC modem converts readings into a communication signal;
• the signal travels through the electrical wiring;
• a compatible concentrator collects the information;
• the data is transferred to the automated metering platform.

Important: the integrated PLC modem is not an internet modem. Centralised data collection requires a compatible PLC concentrator and a configured metering system.

📊 Electricity metering

The EX18 measures active electrical energy and displays accumulated readings on its LCD.

It can be used for time-of-use metering. The actual number of tariffs, switching schedules and available event logs depend on the firmware and configuration.

🔌 Current up to 60 A

A maximum current of 60 A makes the meter suitable for most residential single-phase installations.

The permitted load of the installation must be determined from the electrical design, incoming circuit breaker, cable cross-section and operating conditions.

🖥️ LCD display

Depending on configuration, the display may show:

• accumulated electrical energy;
• tariff readings;
• voltage;
• current;
• power;
• date and time;
• meter identification number;
• service and warning codes.

🏠 Applications

• apartments;
• private houses;
• cottages;
• shops;
• small offices;
• workshops;
• garages;
• internal sub-metering points;
• automated electricity-metering systems.

🌡️ Operating temperature

The stated operating-temperature range is −30 to +70 °C. The meter should be installed in a suitable electrical enclosure protected against water, condensation, excessive dust, overheating and mechanical damage.

🔧 Installation recommendations

• verify compatibility with a 220 V single-phase network;
• compare the current rating with the electrical design;
• disconnect the supply completely before installation;
• use conductors of the required cross-section;
• tighten the terminals correctly;
• install the meter in a protected electrical enclosure;
• connect incoming and outgoing conductors according to the diagram;
• check the LCD after energising;
• register the meter in the PLC system;
• test communication with the concentrator;
• seal and commission the meter as required.

⚠️ Confirm before ordering

• exact EX18 hardware and firmware version;
• accuracy class;
• number of supported tariffs;
• mounting method;
• connection diagram;
• presence of an internal load-disconnection relay;
• operating-voltage range;
• enclosure protection rating;
• verification interval;
• service life;
• supported PLC protocol;
• compatible concentrator model;
• manufacturing and verification dates.

⚠️ PLC performance depends on the electrical network. Noise, filters, voltage stabilisers and some uninterruptible power supplies may weaken or block the communication signal.

⚡ Installation, configuration and commissioning must be performed by a qualified electrician or authorised organisation.
