E3854EL converters are designed to measure and convert electrical parameters in single-phase, three-phase AC electrical networks, as well as other AC circuits into output discrete and analogue signals, transfer the result of measurement and conversion via serial digital interface RS485.
Single-phase converters can be used in three-phase electrical networks for measurement and conversion of parameters of one phase. Three-phase converters are used for measurement and conversion of electrical parameters in three-phase three-wire and three-phase four-wire AC electrical networks.
The possibility of information exchange via RS485 interface, availability of output analogue signals and discrete outputs allow to use the converters in automated systems for various purposes. E3854EL are included in the State Register of measuring instruments of the Russian Federation No. 70318-18. Interverification interval - 10 years.
