Hi Ampers,
I'm hoping there is a transformer guru out there who can help me figure out
how to use a transformer I bought on E-you-know-what. It was billed as a 220 V
primary, 1160 V @2.65 A secondary power transformer, and I am hoping to use
it in a voltage doubler to get about 3000+ VDC for 3-500's or similar.
However, I can't figure out the connections. The leads are marked as follows:
(1) (2) (3) (4)
(5) (6) (7) (8)
50 Hz 60 Hz (Blank) 170 V 185 V
200 V (N/C) 215 V 230 V
==============================================================================
========
50 Hz 60
Hz 1160 V
(A)
(B) (C)
The numbers and letters in parentheses don't appear on the terminal board,
but I identified them here so I could report the DC resistances (and N/C means
there is no wire connected to that terminal), which are as follows:
1 to 2: 0.3 Ohms
1 to 8: 0.75 Ohms
2 to 8: 0.6 Ohms
3 to 8: 0.6 Ohms
4 to 8: 0.55 Ohms
5 to 8: 0.5 Ohms
6 to 8: open circuit
7 to 8: 0.3 Ohms
A to B: 1.1 Ohms
A to C: 9.2 Ohms
B to C: 8.4 Ohms
The transformer is identified as a Type HMB-120-4A, Mfg # KD-14634, Lamp
(blank), Input 200 V, Output 1160 V 2.65 A, Mfg Date 4-01, ORC Manufacturing
Company Ltd.
The only info I can get off the internet is that ORC Manufacturing Company
Ltd makes large scale systems for IC chip manufacturing and such, apparently
using a photoelectric process.
Any ideas as to how to hook this beast up? It's brand new, beautifully
constructed, potted and everything, but am I out of luck in using it for an amp?
Thanks for any help you can give!
Lee, KI7UR
