Shelly Pro EM - 50A - Single-phase WiFi electric current meter

Shelly Pro EM Contactor Control Wi-Fi Energy Meter - 50A

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

• LAN, Wi-Fi and Bluetooth connection for high security and reliability.
• Reports the accumulated energy, as well as the instantaneous voltage, current and active and apparent power per phase in real time
• Power measurement: two independent measurement channels in the same phase
• 4-quadrant measurement with pulsed optical indication of energy usage
• Can be used with contactors for higher loads
• Accuracy Class B (IEC 62053-21)
• Ready for photovoltaics
• It stores data in non-volatile memory that can be recalled for up to 60 days in 1-minute intervals.
• No hub needed Easy control via the Shelly Smart Control app, most platforms and protocols, as well as voice assistants. Use it with Alexa, Home Assistant or your favorite automation system.
• Supports scripting, webhooks, MQTT, WebSocket, HTTPS, UDP, TLS and custom certificates and Modbus TCP protocol.

*Package includes 2 pieces of 50A current transformers.

The Shelly Pro EM-50 device is a two-channel single-phase energy meter, for DIN rail installation. Enhanced with all the flexibility of gen2 firmware and LAN connectivity, it provides professional integrators with additional options for end-customer solutions. It can operate independently on a local LAN and/or Wi-Fi, or can also be operated through cloud home automation services via MQTT, HTTP and WebSocket. All incoming connections support TLS.

The Shelly Pro EM-50 device reports accumulated energy as well as instantaneous voltage, current, active and apparent power per phase in real time. It stores data in non-volatile memory that can be recalled for a period of up to 60 days in 1-minute intervals.

The Shelly Pro EM-50 device has a real-time clock to maintain correct time if connection to an SNTP server is lost.

The User can access, configure and monitor Shelly Pro EM-50 remotely, just as the Device can access and communicate with an automation system, as long as they are on the same network infrastructure.

The Shelly Pro EM-50 device has an integrated Web Interface that can be used to monitor and control the device, as well as adjust its settings.

The Shelly Pro EM-50 device has a built-in relay for contactor control.
