Protection Circuits: The FSQ-series has several self-protective functions, such as Overload Protection (OLP), Abnormal Over-Current protection (AOCP), Over- Voltage Protection (OVP), and Thermal Shutdown (TSD). All the protections are implemented as auto- restart mode. Once the fault condition is ...
