Note 1: UL’s product certification tests were carried out using 20A 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
Note 2: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com)
Note 3: Isolation capacitance can be added external to the module.
