Re: [PSES] Ferrules

Hi Steve: More than you need to know about ferrules and UL 508: https://www.youtube.com/watch?v=3B09qSLek8Q I suspect that few commercially available ferrules are V-0. I found ferrules that were nylon or vinyl. Nylon is HB. However, UL certifies ferrules, UL 486F. Para.

Re: [PSES] Ferrules

The end product Standard usually indicates minimum flame ratings. Also, many Standards allow a end product flame test if the material rating is lower than required. Typically (per UL 746C) – 94HB minimum for attended use products. 94V-2 minimum for unattended use, cord connected products.

Re: [PSES] X-Caps after Diode Bridge

Brian Use of X cap after bridge rectifier is not required. There exist OSM decision that clarifies this. Y caps are required in complete primary circuit towards PE. I hope this helps. Best regards Boštjan Glavič SIQ Poslano iz Outlook za Android

[PSES] X-Caps after Diode Bridge

We use X2 caps in RF filters prior to the Diode Bridge. Do filter caps after the Diode Bridge (DC), but before the isolation transformer, have to be X2? How about filter caps to Chassis/PE after the Bridge? Do they have to be Y-caps? Thanks, The Other Brian PS: We typically buy power
