EM511 Energy analyzer for 1-phase systems, cULus listed, Modbus RTU

EM511 Single-Phase Energy Analyzer

Real energy data. Real control.

Not just another meter.
A tool to understand, optimize, and act.

• → Monitor energy in real time
• → Detect inefficiencies early
• → Integrate into any smart system
• → Make better engineering decisions

What this device actually does

The EM511 is a compact DIN-rail energy analyzer designed for single-phase systems up to 240 V and 45 A.

No external CTs required.
Direct measurement. Clean installation.

You get full visibility of your electrical system:

• Voltage (V)
• Current (A)
• Active, reactive, and apparent power
• Energy consumption (kWh)
• Frequency (Hz)
• Power factor
• Harmonic distortion (THD)

All in real time.

Built for integrators and smart systems

This is where it gets interesting.

The EM511 is not just for reading values.
It’s designed to be part of a bigger system.

• Modbus RTU (RS485)
• M-Bus communication
• Fast refresh (up to 100 ms)
• Easy integration with BMS / SCADA / KNX

Perfect for:

• Smart buildings
• Energy monitoring systems
• EV charging infrastructure
• Automation panels
• Retrofit projects
