The Neptune Ducati APFC Relay is a specific type of electrical relay designed for power factor correction applications in electrical systems. The relay typically includes measurement circuits to monitor the power factor and algorithms to determine when to switch capacitors based on predefined thresholds or settings. It includes features such as overcurrent protection, surge protection, and temperature monitoring to safeguard against electrical faults. The APFC relay is used to automatically control and adjust the power factor of electrical loads. Neptune Ducati APFC Relay automate the process of maintaining a balanced power factor, ensuring efficient operation of electrical equipment and compliance with power quality standards.
