FS: Power transformers

on 2000-09-26 21:02:58 UTC
Hello:

I listed some a while back...I have moved and even after discarding wild
guess 2 tons of power transformers, I have a 2.5 car garage full of
stuff, mostly power xfmrs.

I ran into some I thought had some application to motor drives...they
are unused/surplus/new old stock. At worst, some have slight rust on the
lamination edges, from humidity in warehouse. (not immersion!!!)

Functional satisfaction guaranteed (excluding erroneous orders).

As they are for rectifier applications, DC ratings are given..please
note carefully...they do NOT have embedded rectifiers...just specified
for such applications.

US made, for those of you who want/need to know (cannot certify. Honor
system here.)

I can provide wire color codes, etc.

54-916: Primary: 120/240 V 50/60 Hz, 10 W core loss, 55 deg C temp. rise
Secondary 1: 81 VDC 2.7 ADC (@light load = 0.2 A 92 VDC max) when
using full wave bridge rectifier and bipolar 10000 uF filter caps
Secondary 2: 63 VDC 60 mA using full wave bridge
Secondary 3: 9.3 VDC 300 mA using FW CT rectifier
US$15 each + shipping, several available

54-1042 Primary 120 V 60 Hz...have to go back and check for 240 primary
Secondary: 20 VDC 7A DC
US$8 + shipping, a few dozen available

54-948 Primary 120 V 60 Hz only, 15 W core loss, 50 deg C temp. rise
Secondary 1: 118 VDC 5A DC FWB (@light load = 0.2 ADC 140 VDC max)
Secondary 2: 60 VDC 200 mA
US$35 each + shipping, roughly 6 available...I know where 1 is right at
this moment. These are uglier, but electrical satisfaction guaranteed.

Thanks for the space...hope they are useful to someone...next is eBay.
