EM2172RVV23XOXX CARLO GAVAZZI

EM2172RVV23XOXX, Energy Management Electric Power Meter Model EM21 72R "Retrofit", EM2172RVV23XOXX, Three-phase power meter with detachable front LCD display. The same unit can be used for DIN rail and over-panel mounting. The universal three-phase meter is suitable for measuring both active and reactive electrical energy for cost allocation, although it can also be used for measurement and transmission of electrical variables (transducer function). Box for DIN rail mounting with protection degree (front) IP40. The intensity measurements are carried out by means of external miniature transformers of split core (included) while the voltage measurements are carried out both by means of direct connection and by voltage measurement trafos. The EM21-72R has, as standard, a pulse output for active energy transmission. It also has as an option the RS485 two-wire communication port, EM2172RVV23XOXX, Class A (kWh) according to EN50470-3 standard. Class 2 (kWh) according to EN62053-21.
