Description
The Johnson Controls P28AN-3 Pressure Control Switch is an essentialpart that is control of pressure in HVAC systems. It works at 120 to 240 volts AC and regulates pressures from 8 to 70 PSI with a 60-second delay to ensure precise control. This switch help to regulate the operating conditions of the system and therefore when changes in the system pressure are detected, subsequent action is taken to counter the change. Designed for air conditioning, heat pumps, refrigeration applications and other HVAC-related uses, it enhances system efficiency and reliability.
