Smart 300A Single or Three-phase Energy Meter | LCD and 3x clamp | Tuya Smart Life
This Smart Single or Three-phase 3 x clamp Energy Meter 300A bi-directional is an advanced smart electrical monitoring device designed for installations utilizing a three-phase, four-wire electrical system. It’s often used as a secondary or sub-meter to monitor energy usage and production in commercial, industrial, or residential settings, particularly those with renewable energy sources like solar panels.
Key Features
- Bi-directional measurement: allowing the meter to measure not only the energy consumed (drawn from the grid) but also the energy generated (produced by solar or other sources and exported to the grid).
- 3-Phase 4-wire system: it’s designed for three-phase AC power systems, which typically use three “hot” lines (phases) and one neutral wire.
- Smart connectivity: connects to a 2.4 GHz WiFi network, enabling remote monitoring and control.
- App integration: the unit operates with the Tuya Smart or Smart Life mobile applications, allowing users to:
- View real-time electrical parameters (voltage, current, active power, reactive power, power factor, frequency) for each phase and total.
- Access historical energy consumption and production data (hourly, daily, monthly, yearly kWh).
- Set up automation and smart scenarios linked with other Tuya-compatible smart devices.
- Integrated relay: has a built-in relay which allows the user to turn the power supply on/off for all phases simultaneously.
- Protection and alarm functions: offer over/under voltage protection, overcurrent protection, and current limiting. The device can automatically disconnect power when thresholds are exceeded and send an alarm notification to the user’s phone.
- Accuracy and installation: these are typically DIN rail-mounted for easy installation in an electrical panel and offer high accuracy classes for energy measurement.
