PS03A Automatic Pressure Control Switch for Water Pump 250V 1.1KW — Digital Timer Controller, PURPLE_1

Electronic pressure switch for water systems that automates pump operation based on system pressure. When pressure drops (for example, when a tap is opened) the unit starts the pump; it stops the pump when flow ends (tap closed), all according to the pump pressure thresholds. Designed to replace traditional multi-component control setups (separate pressure switch, pressure tank, check valve, etc.), it simplifies installation and control. The device can also detect low-water conditions and automatically stop the pump to prevent dry running. Configuration options are available to meet user requirements. Suitable for use with self-priming jet pumps, garden pumps, clean water pumps, and similar applications.
