Unitariff meters
 PSCH-4À.05.2Ì PURPOSE AND FIELD OF APPLICATION The meter is intended for accounting of active and reactive electric energy of direct connection in three-phase, three- or four-wire power circuits of a.c. with the frequency of 50 Hz (of the forward direction).
The meters can be used either independently or as a component of any automated information-measuring systems for commercial energy accounting (AIISKUE). NORMATIVE AND LEGAL BACKING IEC 62052-11:2003 TECHNICAL FEATURES - Two or one electrical and mechanical reading device indicates the amount of the consumed electrical energy in kilowatt-hour with the accuracy of up to tenth (PSCH-4À.05.2Ì.302) or hundredth (PSCH-4À.05.2Ì.301) parts of units.
- One (PSCH-4À.05.2Ì.301) or two (PSCH-4À.05.2Ì.302) telemetric outputs.
- LED indication of the current in the load circuit: the more the load, the more often the LED blinks.
- Wired via transformer.
