ALCO PS3-A1S Dual Pressure Switch, 1/2 bar 14.5/29 psig, SPDT, Refrigeration/HVAC, PCN 0714610

ALCO PS3-A1S Dual Pressure Switch - Adjustable SPDT, Refrigeration/HVAC (PCN 0714610)

The ALCO PS3-A1S, identified by PCN 0714610, is a highly versatile and critical dual pressure switch designed for advanced control and safety functions within refrigeration and HVAC systems. This model is engineered to provide precise monitoring and control based on two independent pressure settings (PS: 27 bar/390 psig and PT: 30 bar/435 psig or 1/2 bar setting for different range), offering adjustable cut-out and cut-in limits to protect system components from both abnormally low and excessively high pressures. Featuring a Single Pole Double Throw (SPDT) contact configuration, it offers flexible electrical control, capable of activating or deactivating various system components such as compressors, condenser fans, or alarm circuits. Its robust construction ensures reliable performance and longevity across a wide operating temperature range of -40 to 70°C. Manufactured in the Czech Republic, the PS3-A1S adheres to high-quality standards (CE and cURus listed), making it an essential component for optimizing system efficiency, ensuring operational safety, and extending equipment lifespan in a broad spectrum of commercial and industrial applications.
