E856EL

Direct current and direct voltage measuring converters E856EL are intended for current and voltage measurement in one-phase DC circuits. The converters are used to control current and voltage of electrical systems and installations, for integrated automation of electric power industry facilities, APCS of energy-consuming facilities of different industry sectors, on marine vessels. The converters may be used for operation in the field of defense and safety. The possibility of data exchange through interface RS485 allows using The converters for digital data transmission to APCS. The converters may have a design without interface RS485.
