Hi,
We have seen a Full Bridge for 220V to 28V (back end of 115VAC, 60Hz PFC'd supply).
Its for "Airborne use"
Full Bridge transformer is RM14 with enamelled copper wire (strands) pri and sec, no margin tape, just interwinding tape.
No tubing spec'd for terminations.
1....Do you know what AC isolation voltage the 500Vdc corresponds to? It doesnt say how long the 500Vdc should be applied in isolation test, nor what leakage current is acceptable?
2....Also, do you believe you can officially pass 500Vdc isol test with enamelled copper wire as stated?
(i appreciate it wont blow up in normal use, but is it going to pass the official test?)
115VAC is spec'd to give "1kV max transient"...however , woudl think the PFC output caps would "eat" this.
