Shelly Pro 3EM: Next-generation DIN-mountable 3-Phase Energy Meter
Shelly Pro 3EM is a DIN rail mountable three-phase energy meter. Enhanced with all the gen2 firmware flexibility and LAN connectivity, it provides professional integrators with additional options for end-customer solutions. Shelly Pro 3EM reports accumulated energy as well as instantaneous voltage, current, and power factor per phase in real-time.
- can measure up to 120A per phase and the neutral
- 4 quadrant measurement with multiple connection types
- Accuracy Class B active energy (Compliance with IEC 62053-21 based on manufacturer testing)
- Photovoltaic ready
- Phase sequence error detection (option)
- Optical pulse indication of energy usage
- Measurement accuracy tо 1%
- Stores data in non-volatile memory that can be retrieved for a period of up to 60 days in 1-minute intervals
