[GreenKeys] power transformer

[Jordan Spencer Cunningham]

Hi Ralph,

I got a 0-150V DC PSU from a Chinese seller on eBay. The quality is pretty
good in my experience, and they're much less expensive than the few other
online stores I could find selling anything similar. Heck, even the
shipping was really fast considering it came from China-- I think it only
took a week and change for me to get mine. If you don't want to roll your
own, then this is a great option-- I recommend them. I've had mine in use
with output adjusted to 120VDC limited to around 60-120ma (depending on
whether I'm driving one or two loops simultaneously) since about April of
this year without any problems. You'll have plenty more current at your
disposal than you need (all of their units seem to run with 3-4+ amps
output available), but you can drive multiple loops at once if needed and
could even run a DC reperforator or other DC-powered apparatus.

The seller's name is sheep20110812, and their storefront is here:
https://www.ebay.com/usr/sheep20110812?_trksid=p2047675.l2559.

This model is more or less like the one I got (they seem to change them
from time to time, so I don't think this one is exactly the same):

Here's a cheaper model that only ranges between 100 and 120VDC:
https://www.ebay.com/itm/NEW-AC100-120V-to-150V-DC-3-3A-500W-Output-Regulated-Switching-Power-Supply/173423076000?hash=item2860d222a0:g:zNgAAOxy69JTDg-b

I know there are a couple other sellers on eBay with similar products, but
I took a chance with this one and have been pleased thus far.
