In order to achieve maximum safety and system protection, always use an input line fuse. We recommended a 3.15A time delay fuse for all models. It is recommended that the circuit have a transient voltage suppressor diode (TVS) across the input terminal to protect the unit against surge or spike voltage and input reverse voltage (as shown). The external TVS & input capacitor (Cin) is required if PRFE20W-D series has to meet EN61000-4-4 & EN61000-4-5 The PRFE20W-D series recommended a TVS & aluminum capacitor (120µF/220V) to connect parallel.
