NEVA ST221 2AR2S 28 BCS-G3E MSK multi-tariff optoport. RS-485 modem NB-IoT/GSM for ext. antenna current 5(80) 1ph. Taypit 6197913

Application: In the domestic and industrial sectors for measuring consumed electricity in a single-phase electrical network (manufacturing and commercial enterprises, residential and public buildings, cottages, summer houses, garages, etc.). Purpose: For measuring and accounting of active and reactive energy in single-phase two-wire AC circuits differentiated by time zones of the day, active energy in two directions, and reactive energy (inductive and capacitive). Can be used as a primary sensor in AMR (Automatic Metering Systems), the information from which is read via interfaces. Versions with interfaces: RS-485, NB-IoT/GPRS, LoRaWAN, RF (ZigBee), PLC.
