Note 1: UL’s product certification tests were carried out using 15A fast blow fuse. Fuse interruption characteristics have to be taken into account while
designing input traces. User should ensure that Input trace is capable of withstanding fault currents until fuse blows.
Note 2: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com)
Note 3: Higher values of isolation capacitance can be added external to the module.
