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.
