LEO device for controlling and protecting electric pump against dry running PS-04A 1.1/1.5kW 220~240V/110~120V
LEO PS-04A is an electronic device for starting (opening the tap) and stopping (closing the tap) single-phase electric pumps that responds to changes in pressure and water flow in the water supply system and is used in water supply systems in private homes and small industries. The microprocessor of the pressure regulator LEO PS-04A protects the pump from dry running (when water reappears, the pump starts automatically), providing automatic or manual reset. In addition, the LEO PS-04A pressure regulator protects the pump from over-connection due to small system leaks, and its function is to protect the motor from overload if the set maximum permissible current is exceeded.
