TOMZN DTS238-2L3W WiFi 3 Circuit Smart Energy Meter with CT Clamps

The TOMZN DTS238-2L3W WiFi Smart Energy Meter is an intelligent electricity monitoring device designed to measure and monitor three independent electrical circuits. With three external CT current sensors, WiFi connectivity and RS485 communication, it provides detailed electricity consumption information through your smartphone.

This smart energy meter is suitable for three-phase electrical monitoring applications as well as monitoring three separate single-phase circuits.

Key Features of TOMZN DTS238-2L3W

1. Three Independent Circuit Monitoring

Monitor three separate electrical circuits using the supplied CT clamps. Each circuit has its own energy consumption readings, allowing you to track electricity usage independently.

2. WiFi Smart Monitoring

Connect the energy meter to your WiFi network and monitor electrical parameters through your smartphone. Compatible with Tuya Smart and Smart Life applications.

3. Real-Time Electrical Monitoring

Monitor important electrical parameters, including:

• Voltage (V)
• Current (A)
• Active Power (kW)
• Energy Consumption (kWh)
• Power Factor (PF)
• Frequency (Hz)

4. Three CT Current Sensors

Comes with three external current transformer (CT) clamps for measuring current in three different circuits. Each CT supports up to 100A according to the product’s rated specification.

5. RS485 Modbus Communication

Supports RS485 communication with Modbus-RTU protocol, making it suitable for integration with compatible energy monitoring and automation systems.

6. Import & Export Energy Monitoring

Supports bidirectional active energy measurement, allowing you to monitor electricity imported from the grid and energy exported back to the grid.

7. Energy History & Consumption Tracking

View electricity consumption history through the mobile application, including hourly, daily, monthly and yearly energy records.

8. DIN Rail Installation

Designed for standard 35mm DIN rail mounting, making installation convenient inside electrical distribution boards and control panels.
