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
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.
Note 4: Recommend adding external filter inductor (0.47 µH) between external input capacitance (47 µF) and Bus Qor module.
