ENSIGN CORPORATION
2001-900 B
172.9911

172 is the manufacturer code (Acu-Rite or Ensign?) 9911 is the date code, November 1999. B is the revision level.

Specs:

  • Input Power: 115/230VAC ± 20% @ 50/60Hz
  • Output #1: 7V minimum ripple valley @ 1.4ADC / 47000uF (± 20%) capacitor with 80% nominal input (92VAC instead of 115VAC), 15V ripple peak @ 450mA with 120% (138VAC instead of 115VAC) input.
  • Output #2: 34V minimum @ 115mA DC / 1000uF (± 20%) capacitor with 80% nominal input, no maximum specified.
  • typical forward diode drop is expected to be 1V
  • thermal fuse on each secondary, if it blows it's permanent.
  • external fusing, 0.5A slow blow for 115V operation, 0.25A slow blow for 230V operation.

Transformer pinout:

The bobbin manufacturer and Acu-Rite use different pin mappings. On the bobbin, pin #1 is marked by a notch in the plastic, that pin is also closer to it's adjacent pin than the rest. The bobbin pin numbers are numbered 1-6 then 7-12 clockwise (TODO: from above or below?). In other words, bobbin pins 6 and 7 are across from each other at the same end of the transformer.

Bobbin Pin Acu-Rite Pin Function
1 [NC] [NC]
2 1 Primary #1 A
3 2 Primary #1 B
4 3 Primary #2 A
5 4 Primary #2 B
6 [NC] [NC]
7 5 >34V out
8 6 >34V out
9 [NC] [NC]
10 [NC] [NC]
11 7 7-15V out
12 8 7-15V out
  • For 115V operation, jumper Primary #1A to Primary #2A as well as Primary #1B to Primary #2B. This puts the primaries in parallel.
  • For 230V operation, jumper Primary #1B to Primary #2A. This puts the primaries in series.
