ICOM A23 Transformer Specs
Would someone please give me the specs for the AC-DC transformer for
the ICOM A-23? I've misplaced mine and ICOM wants $40 for a replacement. I can probably do better with a generic one from Radio Shack. I need to know the polarity, DC voltage, and amps. Thanks (Sorry for the cross-post to rec.aviation.piloting, but that group seems more active than the rest.) |

Gosh... That'd cost an extra 20c and might use around 1 sq cm of board space. ! _________________________________________ Usenet Zone Free Binaries Usenet Server More than 140,000 groups Unlimited download http://www.usenetzone.com to open account |

Voltage drop. Even low-voltage schottky diodes will drop 0.3-0.4V. That's like throwing away 33% of your 1.2v battery capacity. -Cory -- ************************************************** *********************** * Cory Papenfuss, Ph.D., PPSEL-IA * * Electrical Engineering * * Virginia Polytechnic Institute and State University * ************************************************** *********************** |
