EM50 Energy analyzer for 3-phase, 2-phase and 1-phase systems Benefits Flexible installation. EM50 is suitable for single-phase, two-phase, three-phase and wild-leg systems with different voltage levels used in USA and Canada. Selectable communication protocol. Modbus RTU and BACnet MS/TP in the same unit. Extended energy measurements. 4-quadrants reactive power and multi-tariff metering. Easy navigation. The slideshow function automatically displays the desired measurements in sequence without having to use the keypad. Legal metrology. The Measurement Canada version can be used for legal metrology in Canada. Quick configuration. The proprietary UCS configuration software is free and permits quick system configuration. Description EM50 is a three-phase energy analyzer for DIN- rail mounting with LCD display. It is equipped with a static output (pulse transmission), a relay output (alarm or remote control function) and Modbus RTU or BACnet MS/ TP port. EM50 manages direct voltage connection up to 600 V L-L or by means of voltage transformers. The current measurement is carried out via 5 A current transformer, 333 mV or 80 mA (Measurement Canada only) current sensor or Rogowski coil. Applications EM50 is the perfect solution especially in building and industrial automation where energy and main electrical variables monitoring is required. It is particularly suited for energy efficiency monitoring, cost allocation, and fiscal/legal sub-billing, where the Measurement Canada approval is required. Main functions Measure energy consumption and main electrical variables of single-phase, two-phase or three-phase loads Display single phase and total variables Transmit data via serial communication (Modbus RTU or BACnet MS/TP) Transmit energy consumption via pulse output Transmit alarm and manage remote control via relay output Manage monthly energy log (current month and the previous two months) Manage event log database (resets, terminal cover openings, configurations, alarms, etc.) 24/05/2021 EM50 DS ENG Carlo Gavazzi Controls S.p.A. 1EM50 Main features Energy measurements: imported and exported kWh, 4-quadrants kvarh and 4 tariffs energy meters single phase measurements Selectable DMD calculation method (fixed, sliding, sliding with selectable refresh time or thermal) Real time clock and tariff management 24/05/2021 EM50 DS ENG Carlo Gavazzi Controls S.p.A. 2
