Wi-Fi Energy Meter with Contactor Control

Shelly Pro EM-50 is a DIN rail mountable two-channel, single-phase energy meter. It has an integrated switch with dry contacts for contactor control.

KEY FEATURES

  • LAN, Wi-Fi and Bluetooth connection for high security and reliability
  • Reports accumulated energy, as well as instantaneous voltage, current, active and apparent power per phase in real time
  • Power metering – two independent measurement channels on the same phase
  • 4 Quadrant measurement with optical pulse indication of energy usage
  • Can be used with contactors for bigger loads
  • Accuracy Class B (IEC 62053-21)
  • Photovoltaic ready
  • Stores data in non-volatile memory that can be retrieved for a period of up to 60 days in 1-minute intervals.
  • No hub required! Easy control through the Shelly Smart Control app, most platforms and protocols, as well as voice assistants. Use it with Alexa, Home Assistant, or your preferred automation system.
  • Supports scripting, webhooks, MQTT, WebSocket, HTTPS, UDP, TLS and custom certificates & Modbus TCP protocol

NOTES

  • Standard warranty (included in purchase price): 5 Years warranty through manufacturer due to device malfunctions when it is used in user manual described conditions.
