PS32 Dual Pressure switch
This switch is suitable for controlling gas, water, and oil pressure in addition to refrigerants.
PS32 Dual Pressure Switch is designed for pressure control in refrigeration and air conditioning systems, offering protection against low suction pressure and high discharge pressure. It supports direct connection to single-phase AC motors up to 2 kW or integration into control circuits for DC and larger AC motors. Featuring a compact design and SPDT mechanism, the PS32 ensures reliable system operation with optional enclosure ratings of IP20, IP30, and IP44.
Key Specifications:
• Core Function: Dual pressure control for refrigeration/air conditioning systems
• Switch Mechanism: Single-pole double-throw (SPDT) with snap-action function
• Mounting: Compact form with vibration-resistant design
• Compatibility: HVAC compressors, air-cooled condensers, and control circuits
