EX518 U 380 V, 100 A three-phase electricity meter with PLC module

⚡ The EX518 U is a multifunction electronic meter designed for energy measurement in a three-phase four-wire network.

It supports direct connection of loads up to 100 A per phase.

🔌 Main electrical ratings

• number of phases — three;
• network — three-phase, four-wire;
• line voltage — 380 V;
• maximum current — 100 A per phase;
• frequency — 50 Hz;
• connection — direct.

No external current transformers are required for this direct-connected version.

📡 PLC communication

The PLC module transmits readings through existing mains wiring to a compatible data concentrator.

No SIM card is required inside the meter for PLC communication.

🌐 AMR operation

Remote reading requires a compatible PLC concentrator, matching communication protocol, server software and meter registration.

According to Schetchik.uz, this version supports the Tashkent city AMR system. A separate GPRS module may be required for regional installations.
