perature with appropriate power derating. Specifications subject to change without notice.
Parameter
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 until fuse blows.
Note 2: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: [e-mail])
Note 3: For modules with isolation voltage rating of 2250V, order the Feature Set option C. See last page for ordering details.
Note 4: Higher values of isolation capacitance can be added external to the module.
