PC4713-W-E-TY/3W three-phase 3-wire energy meter with three split-core CT clamps on leads

PC4713-W-E-TY/3W

Three Phase WiFi + Ethernet Smart Energy Meter

Built for 3-phase 3-wire and Delta supplies (156-480 V L-L): Tuya metering over Ethernet or WiFi, three 750 A CTs, bidirectional energy.

Overview

PC4713-W-E-TY/3W is the one model in the OWON three-phase range built for a three-phase three-wire or delta supply. The other six are specified for three-phase four-wire; this one covers that as well as split-phase and single-phase, so a single SKU spans every common supply arrangement.

It is also the model the case change came with: a 1P DIN module 19 mm wide, 19 × 69 × 90 mm overall, for boards in the European market. Its voltage window is the widest in the range — 90–277 Vac line-to-neutral and 156–480 Vac line-to-line — with bidirectional measurement on three CTs from 80 A to 750 A.

Where the PC4713-W-E-TY/3W Sits in the Range

This model exists because a three-phase three-wire or delta service cannot be metered by hardware designed around four-wire measurement, and the rest of the Tuya line is four-wire hardware. Where a project is on a four-wire supply, the PC4713-W-E-TY/R is the fuller specification — it adds the dry-contact relay to the same Ethernet and Wi-Fi connectivity.

The 3W build is also the narrowest case in the family, at 19 mm on the rail, for boards where a wider instrument will not fit. As with the other Tuya models, the data destination is fixed at the Tuya Cloud; keeping readings on your own server means the PC4713 Open API series, PC4713-W or PC4713-W-485.

PC4713-W-E-TY/3W Platform and Integration Notes

Reports into the Tuya Cloud, read in the Tuya App. Live values and history by day, week, month and year, with grid and energy values exportable to and importable from other Tuya devices for automation.

Offline storage with automatic re-report. Readings are held locally and re-sent once a network path returns, so a dropout does not become a gap in the record.

Notification and language coverage. Alerts are pushed to the App, which is available in German, French, Spanish and Italian as well as English — the languages a European installation is most likely to need.

Reactive and apparent power on the home screen, so power factor is visible without opening a report.

Standard Tuya DPs keep Home Assistant working. Standard data points are used wherever possible, with custom DPs only where needed.

PC4713-W-E-TY/3W Limits and What to Specify Instead

  • Relay output — not fitted. Load switching is available on the PC4713-W-E-TY/R and PC4713-W-TY/R.
  • Any destination other than the Tuya Cloud — the PC4713 Open API series reports to your own cloud or local server.
  • RS485 / Modbus RTU — not offered in the Tuya range. The PC4713-W-485 carries the serial bus.

Wiring & installation

Filmed on a live panel: three phases with no neutral, L1 to A, L2 to B, L3 to C, and only two CTs on IA+/- and IC+/- — the middle phase carries no clamp.

Isolate the supply before touching any conductor. Wire colours in the clip are the demo panel's, not a requirement.

Key Benefits

1P (19 mm) Case for European Boards

A single DIN module, 19 mm wide and 19 x 69 x 90 mm overall, with plug-in power and CT terminals so the unit can be mounted first and wired after.

3P3W, Delta and 3P4W Hardware

The one model in the range built for three-phase three-wire and delta supplies, and it also covers three-phase four-wire, split-phase and single-phase.

Wi-Fi and Ethernet Running Together

Both links active at once — Wi-Fi where cabling is impossible, Ethernet where wireless is poor.

Data Export and Data Erase Without Re-Pairing

Export per-phase energy hour by hour within a day or day by day across a range, up to one year; erase stored data while keeping the Wi-Fi pairing.

Frequently Asked Questions

Which supply arrangements does the 3W actually cover?
Three-phase three-wire (delta), three-phase four-wire, split-phase and single-phase. The voltage window is the widest in the range: 90-277 Vac line-to-neutral and 156-480 Vac line-to-line, which is what the delta connection needs.
Why is it only 1P (19 mm) wide, and will it fit a European board?
European boards were the driver for this mould: a 1P module, 19 x 69 x 90 mm on 35 mm DIN rail, fits where a wider instrument will not.
The terminals are plug-in — what does that change on site?
Power and CT connections are made through removable male/female terminal blocks, so the main unit can be fixed and wired first and the terminal blocks inserted afterwards — useful when panel work is done in stages.
How do I commission the network the first time?
Download the Smart Life app, then either scan the QR code on the device or use Bluetooth pairing. For Wi-Fi you need the 2.4 GHz network name and password; for Ethernet, plug in an internet-enabled cable. If no device is detected, press and hold Reset for 5 seconds until the Net LED blinks slowly, then try again.
Which CT ratings and apertures are available?
80 to 750 A in six steps, with bores of Ø10 / 16 / 20 / 24 / 36 / 51 mm. This model uses three clamps.
How accurate is it?
Voltage ±1%; current ±1% at rated current and ±2% at low current, banded per clamp.
Should I take this or the PC4713-W-E-TY/R?
By the supply. On a three-phase three-wire or delta service only this model works — the four-wire hardware cannot meter it. On a four-wire board that also needs the dry-contact relay, the PC4713-W-E-TY/R is the fuller specification.
Is the App localised for European installers?
Yes. German, French, Spanish and Italian in addition to English, and alerts are pushed to the App.
Does it need a gateway?
No. Wi-Fi or Ethernet connect directly; a gateway is only needed for ZigBee devices.
