Prepaid energy meters


Incotex 233



The multifunctional electric energy meter INCOTEX 233 is intended for one or bidirectional metering of active and reactive electrical energy and power in three-phase 3 or 4-wired AC mains directly with the possibility of zone tariff metering, longtime storage and transmission of collected information to information collection centers over digital interface wire or wireless communication channels.

INCOTEX 233 has features of a prepaid electricity meter.

INCOTEX 233 records the consumed electricity, performs credit management and internal contactor for switching the load.
