Models which are not more series-produced PSCH-4À.05.2 PURPOSE AND FIELD OF APPLICATION The meter is intended for accounting of active electrical energy in three-phase, three- or four-wire power circuits of a.c. with the frequency of 50 Hz. It can be used either independently or as a component of any information-measuring systems. NORMATIVE AND LEGAL BACKING IEC 62052-11:2003 TECHNICAL FEATURES - The electrical and mechanical reading device indicates the amount of the consumed electrical energy in kilowatt-hour with the accuracy of up to tenth or hundredth parts of units depending on nominal voltage.
- LED indication of the current in the load circuit: the more the load, the more often the LED blinks.
- Two telemetric outputs for commercial and technical accounting.
- When manufacturing printing boards, SMD assembling technology is used.
