Description
The Shelly Pro EM-50 is a single-phase, two-channel, DIN-rail mountable energy meter. Enhanced with the flexibility of gen2 firmware and LAN connectivity, it provides professional integrators with additional options for end-user solutions.
It can operate autonomously on a local LAN and/or Wi-Fi network, or it can also be used via cloud home automation services via MQTT, HTTP and WebSocket. Please note that all incoming connections support TLS.
The Shelly Pro EM-50 reports accumulated energy, as well as instantaneous voltage, current, active and apparent power, per circuit and in real time. It stores data in non-volatile memory at 1-minute intervals that can be retrieved for up to 60 days.
FEATURES:
◾ Measurement of power and energy in 2 circuits (in the same phase);
◾ Measurement in 4 quadrants (consumed/generated and reactive inductive/capacitive);
◾ Shows values per circuit and in real time;
◾ Values of accumulated energy, instantaneous voltage, current, active and apparent power;
◾ Stores data in non-volatile memory, minimum resolution of 1 minute (up to 60 days);
◾ Accuracy class B (IEC 62053-21)
◾ Prepared for photovoltaic energy systems
◾ Wi-Fi, LAN and Bluetooth connectivity
◾ Simultaneous use of Ethernet and Wi-Fi
