SAGINOMIYA DNS-D306Q13A Dual Pressure Controller (High-Low Pressure Switch)

The SAGINOMIYA DNS-D306Q13A is a dual-pressure auto-reset controller designed for refrigeration, air conditioning, and marine systems. It monitors both high and low pressure via two separate pressure inlets, with adjustable setpoints for pressure thresholds. The auto-reset feature automatically restores operation once pressure returns to the normal range, eliminating the need for manual reset. Certified for industrial and marine use, it protects compressors and systems from damage caused by overpressure or underpressure, ensuring stable and safe operation in harsh environments.
