Product information

Description

The TUYA Smart Energy Monitor 3P+N 120A DIN Wi-Fi is an advanced three-phase power and energy metering device designed for efficient DIN rail mounting. It consists of a main monitoring unit and three split-core current transformers, allowing users to effectively and accurately track energy consumption in three-phase systems with a neutral wire, as well as in single-phase systems. By utilizing wireless connectivity through 2.4GHz Wi-Fi, this smart energy monitor seamlessly integrates with the Tuya platform, enabling remote energy consumption monitoring, real-time power tracking, and smart home automation applications.

Advantages

This smart energy monitoring device offers comprehensive tracking capabilities for real-time voltage, current, power, electricity consumption, and frequency measurements. With support for current measurement up to 120A per phase, it ensures accurate monitoring in both residential and commercial facilities. The included split-core current transformers feature a 16mm diameter, permitting quick and convenient installation without the need to interrupt the existing electricity supply. Furthermore, three independent detection modules monitor each phase separately, helping to identify energy consumption irregularities efficiently. Compatibility with Android and iOS devices via the Tuya Smart or Smart Life app, alongside voice control support for Amazon Alexa and Google Assistant, provides exceptional daily convenience.

Suitable for

  • Monitoring energy consumption in three-phase electrical systems with a neutral wire
  • Tracking power usage in single-phase electrical systems
  • Residential homes, apartments, and multi-family buildings
  • Commercial facilities, offices, and small business workshops
  • Smart home automation projects and energy-saving setups

When it may not be suitable

This device is not designed for industrial environments requiring measurement exceeding 120A per phase or specialized high-voltage setups. It is also unsuitable for outdoor installations without an appropriate weatherproof enclosure, as the device features an IP20 protection class.

Key specifications

  • Maximum current: 120 A per phase
  • Operating voltage: 220 to 240V AC phase-neutral and 380 to 415V AC phase-phase
  • Frequency: 50 or 60 Hz
  • Energy measurement accuracy: Class 1, 1 percent
  • Connection type: Wi-Fi 2.4 GHz
  • Supported applications: Tuya Smart and Smart Life for Android and iOS
  • Voice control compatibility: Amazon Alexa and Google Assistant
  • Mounting type: DIN rail
  • Protection class: IP20
  • Operating temperature range: -25 degrees Celsius to +70 degrees Celsius

How to use

Begin installation by securely mounting the monitoring unit onto a standard DIN rail within your electrical panel. Attach the three split-core current transformers around the phase cables according to your electrical system configuration, ensuring safe handling without disrupting the main power supply if applicable. Connect the device to your local 2.4GHz wireless network and pair it with the Tuya Smart or Smart Life application on your mobile device. Once successfully connected, you can configure your monitoring preferences, view real-time data measurements, and set up integrations with compatible voice assistants.

What to consider before purchase

  • Verify that your electrical system parameters match the operating voltage and current limits of the device
  • Ensure you have a stable 2.4GHz Wi-Fi signal available near your electrical panel
  • Confirm physical space availability on the DIN rail for the main monitoring unit
  • Check that the 16mm diameter of the split-core current transformers fits your existing cables

Usage recommendations

Regularly review real-time data and historical consumption trends through the mobile application to identify abnormal energy usage and optimize overall power efficiency in your facility.
