Box of management Ya5111

Box of management Ya5111 Boxes of the Ya5111 series of stations of management of submersible pumps are intended for remote and local control of three-phase electric motors of submersible pumps and protection them at overloads on current, not the full-phase mode, inadmissible decrease in the feeding tension and work in the mode of "the dry course". The station provides: - power off of station at short circuits in loading; - shutdown of the electric motor of the pump at an overload; - will lock inclusions and shutdown of the electric motor at decrease in water level in a well below the worker - "the dry course". - will lock operation of the electric motor at not full-phase mode of a power line; - over 20% will lock operation of the electric motor at decrease (the general or one of phases) tension of a power line; - a ban of launch of the electric motor at incorrect alternation of phases of a power line; - indication of the included condition of the pump, disconnection from "the dry course", malfunctions of a power line and an overload; - measurement of the consumed current in one of electric motor phases; The station is intended for operation in the enclosed space without artificially adjustable climatic conditions: - air temperature from minus 45*C to plus 40*C; - relative humidity of air to 98% at a temperature plus 25*C; - height above sea level to 1000 m; Environment is not explosive, not containing conducting dust, aggressive gases and vapors.
