The LFDS630 modernizes compressor and pneumatic system pressure regulation by replacing mechanical spring-loaded switches with an all-electronic solution. A high-reliability pressure sensor, high-contrast LCD display, and 10 A relay output are integrated into a single compact unit — delivering precise, drift-free pressure control with simple push-button configuration.

How does automatic pressure regulation work?

The controller continuously monitors system pressure. The user sets two values — Hi-P (stop pressure) and Lo-P (start pressure). When pressure reaches Hi-P, the internal relay cuts power to the compressor. When pressure drops to Lo-P, the relay reactivates the motor. This two-setpoint logic enables fully automatic, energy-optimized pressure regulation without the mechanical hysteresis and drift of traditional spring-loaded switches.
