DescriptionElectronic counters CE 303S31 746 JAVZ All payment methods: uzkart (online), cash, transfer. The warranty is 3 years. THE SERVICES ARE LICENSED. THE PRODUCT IS CERTIFIED. The meter is a three-phase, universal transformer or direct connection, designed to measure active and reactive electrical energy, power, voltage frequency, active and reactive power coefficients, angles between phase voltage vectors and phase current and voltage vectors, RMS voltage, current strength. The meter has the ability to organize multi-tariff electricity metering with the transmission of accumulated information via an optoport, RS485 interface, radio, PLC or GSM/GPRS modems.
