[Amps] Chinese 15KV 2A rectifier modules?

[Jim Barber]

Has anyone had any experience (good or bad) using the Chinese 15KV, 2A 
rectifier modules that were selling on eBay a while back? The part 
number printed on the side is PRHVP2A-20 .

I bought a handful a year or so ago when I was building my hi-pot 
tester. They seem to handle high voltages without issue, (my hi-pot 
works fine past 10KV) but seem awfully small for the 2A current rating.

The reason I ask is because I've been contemplating building yet another 
6A10 rectifier board for a single 8877 I'm working on. The modules would 
be easier/smaller, but since the encapsulated part is only (roughly) 
1.5" x .5", I'm thinking the ratings may be too good to be true.

Thanks,
