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.
