Sanhua PSV15AML-S51 Dual Pressure Switch

The SAN-PSV15AML-S51 is a Sanhua dual pressure switch designed to monitor low and high refrigerant pressure in heating, ventilation, air conditioning and refrigeration (HVAC/R) systems. It helps protect compressors by switching electrical contacts when refrigerant pressure reaches the configured limits.

The low-pressure section features automatic reset, while the high-pressure section features manual reset. This allows the low-pressure control to reset automatically when conditions return to the required range, while the high-pressure control requires manual intervention after a pressure trip.

FEATURES:

• Dual low-pressure and high-pressure monitoring
• Automatic reset for the low-pressure section
• Manual reset for the high-pressure section
• Low-pressure range of −0.5 to 7 bar
• High-pressure range of 6 to 32 bar
• Fixed high-pressure differential of 4 bar
• SPDT electrical switching contacts
• Flare pressure connection
• Designed for compatible refrigeration and air conditioning systems
