Shelly
Energy meter DIN Pro EMArt. no.: 0900471
The Shelly Pro EM-50 is a two-channel single-phase energy data meter, which uses current transformers to measure energy data with loads up to 50A and with 99% accuracy. The device measures power, current, voltage and power factor with a resolution of one minute with real-time measurement. Shelly The Pro EM-50 also has a built-in 2A potential-free contact set, which can be used to draw an external contactor for controlling larger loads.
The Shelly Pro EM-50 can be easily set up and controlled through the Shelly Smart Control app or your preferred smart home system. Shelly devices work 100% locally and only need a local network to work. Shelly can be used alone in the Shelly Smart Control app or with more than 200 partner systems such as Google Home, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey and many more.
The Shelly Pro EM-50 is designed for mounting on a DIN rail and is supplied including two current transformers. The device reports power measurement (W), voltage measurement (V), current measurement (A), apparent power (VA) and power factor (PF) in real time and stores the measurements for up to 60 days on the device and for 365 days when connected to the Shelly Cloud app . The device also meets the requirements of IEC 62053-21 with an accuracy corresponding to Class B (maximum 1% deviation). The Shelly Pro EM-50 also has a built-in real-time clock, so it can maintain the time and date in the event of a loss of connection to an SNTP server.
The Shelly Pro EM-50 can be connected to the Internet or the local network through LAN interface and/or 2.4 GHz WiFi. In addition, the device has built-in Bluetooth, like the rest of the Pro and Plus devices, which means it can also be used as a gateway for Shelly's Bluetooth devices.
Shelly Pro EM-50 works locally without connecting to Shelly Cloud, but it is recommended to enable this for easy data storage and increased functionality. The device can also communicate via MQTT, HTTP and WebSocket. All support TLS.
