Designed for measuring active and reactive energy of forward and reverse directions and four-quadrant reactive energy, keeping arrays of load power profile with programmable integration time, measuring parameters of three-phase network and quality parameters of electric energy in three-wire and four-wire AC networks. It allows to organise multi-tariff metering with transmission of accumulated information via wireless communication channels.
The device is developed on the Russian component base and has a microprocessor K1986VU024 (NARTIS Ltd.). The W133 meter housing is compact, for installation in a panel.
Communication interfaces: Opto-port, RS-485, RF, GSM, NBIoT. 4 tariff zones.
Built-in load control relay, designed to switch the phase current circuit of the meter.
