DTS238-2L3W Three Circuit Single Phase WIFI Smart energy meter

General

TOMZN DTS238-2L3W is a WiFi-enabled smart energy meter designed for single-phase systems with three independent measurement circuits. It allows real-time monitoring of voltage, current, active/reactive power, power factor, frequency, and bidirectional energy via the APP. The APP also supports historical energy tracking (hour/day/month/year), exportable Excel reports, separate import/export energy display for solar applications, and per-circuit alarm settings for overvoltage, undervoltage, and overload. Alarm events and on/off operation records are logged separately for each circuit. Energy data is retained in memory during power loss or WiFi disconnection and syncs automatically upon reconnection. The meter also features a pulse LED, loss phase indication, and reliable long-term operation without calibration drift. It installs easily on a 35mm DIN rail.

Basic Function

1. The APP display three circuit single phase positive active energy, negative active energy

2. The APP also display three circuit single phase real voltage, current, active power, reactive power, power factor, frequency

3. Hour/Day/Month/Year history active energy consumption tracking by APP, and also can output 28-31 days day kWh excel records by email.

4. APP has overvoltage /under voltage/overload alarm for three circuit each phase separately, it can set value by APP. Each alarm function can be opened/closed by APP

5. Alarm event records and on/off operation records on APP for three circuit each phase separately

6. Energy data can store on memory chip when power off, it also still measure energy when lose WIFI connection and it will update the energy on APP when connect WIFI again

7. It can reset the active energy to zero from APP for three circuit each phase separately, you should delete device from APP and connection WIFI again after reset energy to zero.

8. APP have active power 15minutes interval curve only one day for three circuit each phase separately

9. It have energy consumption cost and carbon emission on APP for three circuit each phase separately

10. It suit for solar power generation using, Import energy and export energy display separately on APP and RMS active power will display positive and negative symbols on APP

11. Pulse LED indicates working of meter

12. Lose phase indication, and still measure lose one or two phase under three phase four wire connection

13. Measuring active energy without calibration under long term operation

14. 35mm din rail installation
