3 phase wifi power meter with no screen

This DIN rail-mountable smart energy meter (models ATMS100133 for WiFi or ATMS100133Z for Zigbee) provides comprehensive three-phase electrical monitoring. Non-invasive installation is achieved using detachable, clamp-style Current Transformers (CTs) that encircle conductors, measuring current flow on each phase (L1, L2, L3) and neutral (N), clearly illustrated in its connection diagrams. It supports bidirectional energy metering, crucial for tracking both grid consumption and reverse energy flow from sources like solar panels.

The device connects wirelessly via WiFi 2.4GHz or Bluetooth/Zigbee for seamless data transmission. Its dedicated mobile application delivers extensive real-time metrics for each phase and totals, including: Voltage (V), Current (A), Active Power (kW), Reactive Power (kVar), Power Factor, Total Active Energy (kWh), plus distinct Positive and Reverse Active Energy readings. This granular data allows for detailed power quality analysis and consumption tracking.

Rated for voltages between 100-240V AC (50/60Hz) and currents from a minimal 0.02A up to 100A, it operates reliably in ambient temperatures from -20°C to +60°C. The compact unit consumes minimal power itself (2.2VA/0.7W). Key features include the ability to share the monitored data securely with up to 20 authorized users via the app. Physical dimensions are specified (e.g., main unit approx. 90x65.5x18mm), ensuring compatibility within electrical panels.
