The
electronic head pressure control modulates condenser fan motor speed by varying
the air volume through the condenser. The control monitors the head pressure by
sensing the sub-cooled liquid line temperature.
Applications
Typically
utilized on air-cooled condenser fan motors in air conditioning and refrigeration systems.
Applicable
Motors
• Single phase single speed
• Open frame
