PS03A Automatic Pressure Control Switch for Water Pump 250V 1.1KW — Digital Timer Controller, Easy to Use (BLUE_1)

Electronic pressure controller for water systems — Model PS03A. This unit automatically starts the pump when system pressure falls (for example, when a tap is opened) and stops the pump when flow ends (tap closed), operating to the pump pressure settings. It replaces conventional multi-part control setups (pressure switch, pressure tank, check valve, etc.), simplifying installation and control. Protects the pump from dry-run by automatically stopping operation when water is scarce. Configurable to user requirements and supplied with a digital timer-based pump controller for straightforward operation. Applications: self-priming pumps, jet pumps, garden pumps, clean water pumps, etc.
