The Controlmatic A203120 is a robust automatic pressure controller designed for single-phase water pumps, capable of managing up to 1.5kW (2HP) and 12 Amps at 230V. This essential unit replaces traditional pressure tanks, pressure switches, and check valves, simplifying pump system management. It intelligently starts the pump when system pressure drops (e.g., when a tap is opened) and stops it when flow ceases (e.g., when a tap is closed). Key features include integrated dry run protection to safeguard the pump from damage, a built-in check valve, and a manual reset function. With a maximum operating pressure of 10 Bar and an IP65 protection rating, this Controlmatic pump controller ensures reliable and durable performance in various demanding conditions. It features standard 1-inch BSP male inlet and outlet connections.
