Unitariff meters SEO-1.15 meter PURPOSE AND FIELD OF APPLICATION The meters are designed for metering of active electrical energy in two-wire power circuits of alternating current with the frequency of 50Hz. NORMATIVE AND LEGAL BACKING
IEC 62052-11:2003 TECHNICAL FEATURES - The electrical and mechanical reading device or liquid-crystal display indicates the amount of the consumed power in kilowatt-hour with the accuracy of one hundredth of a unit.
- LED indication of the current in the load circuit: the more the load, the more often the LED blinks.
- Reading devices with the reverse motion lock and protection from electromagnetic influences are used in the electricity meters.
- The meters SEO-1.15.702, SEO-1.15.702/1 have two devices for electrical current measurement – in the phase and null line, what ensures energy metering when current is available in any connection line.
- The electricity meters have telemetric data output, which ensures transmission of information on the quantity of active energy to a remote data collection system through a two-wire communication line.
- When manufacturing printing boards, SMD assembling technology is used.
