PC4711-W-TY/3CT
Single-Phase Multi-Channel Smart Energy Meter
Three single-phase circuits in one Tuya meter: three CTs measured independently, no Ethernet, and a lower host cost than a three-phase meter.
Overview
PC4711-W-TY/3CT is the multi-channel member of the single-phase range. It takes three open-type CT clamps where the other models take two, and reads each circuit independently, so three separate single-phase loads or tenants come from one 19 mm module instead of three.
The distinction that matters: this is three single-phase circuits, not a three-phase meter. There are no phases to configure and no phase-to-phase voltage to measure - which is why it is the cheaper route for three single-phase circuits, and why a three-phase service still needs a PC4713. Platform otherwise unchanged: 90-277 V input, CTs 80 A to 300 A, bidirectional metering, 15-second Tuya reporting.
PC4711-W-TY/3CT Platform and Integration Notes
Where the cost saving comes from. Three single-phase circuits metered by one module costs less than a three-phase instrument, because there is no phase-to-phase voltage measurement and no phase configuration to carry.
Offline storage, so a dropout is not a gap in the record. Readings are held locally and re-reported automatically once the network returns.
CT setting, data erase and remote reboot from the App. A channel can be re-ranged or the record cleared without a site visit.
Tuya App, and Home Assistant. All three circuits are read in the Tuya App, and all three are also available in Home Assistant.
PC4711-W-TY/3CT Limits and What to Specify Instead
- Three-phase measurement — this is three single-phase channels, not a three-phase meter. A three-phase four-wire, split-phase or 3P3W service needs the PC4713 range, and a 3P3W or delta supply specifically needs the PC4713-W-E-TY/3W.
- Relay output — not fitted. Load switching is on the PC4711-W-TY/R and PC4711-W-E-TY/R.
- Ethernet — not available on the three-CT model; the two-CT PC4711-W-E-TY offers the wired port.
- Your own server as the destination — PC4711-W or PC4711-W-485 from the Open API range.

Key Benefits
Three Circuits in One Module
Three open-type CT channels read three single-phase circuits separately instead of one combined total.
Three Single-Phase Lines, Not a Three-Phase Meter
It does not measure phase-to-phase voltage: there are no phases to configure, which is what makes it cheaper for a three-circuit job.
CTs 80 A to 300 A, Clipped On
No circuit is cut, and the three circuits can mix load and generation because measurement is bidirectional.
Data Export With Day-to-Year History
Export from the App with history by day, week, month and year for all three circuits.
Ideal For
Common deployment scenarios where Single-Phase Multi-Channel Smart Energy Meter delivers the most value.
Three Single-Phase Circuits, One Meter
Three tenants, three loads or three distribution ways metered separately without three devices.
Per-Load Analytics
Separate traces for generation, HVAC and general load instead of one combined figure.
Buildings Without Three-Phase Supply
Where the requirement is three single-phase circuits rather than one three-phase service.
Cost-Sensitive Multi-Circuit Jobs
A three-phase meter would be over-specified and more expensive for the same three circuits.
Mixed Load and Generation
Bidirectional measurement means a generation circuit can sit alongside load circuits.
Distributor and OEM Programmes
Neutral standard units, with branding and packaging available.
