The Shelly Pro EM-50 is capable of monitoring up to 50 amps of electrical current, making it suitable for smaller circuits or systems, as well as featuring two independent measurement channels on the same phase for independent power monitoring of multiple devices. The device itself also includes 2 x 50A clamps, offering safe and accurate energy consumption monitoring over both channels. The Shelly Pro EM can also be used with contactors for larger loads, and can store data in non-volatile memory that can be retrieved for a period of up to 60 days in 1-minute intervals. Like the rest of Shelly's portfolio, the Pro EM is compatible with a wide range of Smart Home and Voice controlled assistants like Amazon Alexa or Google Home.
