Shelly Pro EM-50 Energy Meter with Contactor Control
Shelly Pro EM-50 is a DIN-rail energy meter with two independent measurement channels for circuits on the same phase. Supplied with two 50 A current transformers, it reports voltage, current, active and apparent power and accumulated energy, making it suitable for detailed load monitoring, photovoltaic applications and energy-management automations.
Ethernet, Wi-Fi and Bluetooth connectivity are built in, and the meter can work with contactors when control of larger loads is required. Shelly specifies Class B measurement accuracy and local non-volatile data storage for up to 60 days at one-minute intervals.
