PS03A Automatic Pressure Control Switch 250V 1.1KW — Adjustable Water Pump Controller with Digital Timer

Electronic pressure control switch designed for water systems. The PS03A monitors system pressure and automatically starts the pump when pressure drops (for example, when a tap is opened) and stops the pump when flow ceases (tap closed), operating to the pump's pressure standard. It replaces a conventional pump control assembly — pressure switch, pressure tank, check valve, etc. — simplifying installation and control. The controller prevents the pump from running dry by stopping operation when water is scarce and offers configurable settings to suit user requirements. Suitable for use with self-priming pumps, jet pumps, garden pumps, clean water pumps and similar applications.
