| 286746 | 2004-11-01 09:45:00 | I believe the PSU was previously used with the modem. Can it do any damage? What about a 16v DC power supply? | bpt1 (419) | ||
| 286747 | 2004-11-01 09:50:00 | IF the modem uses any inductive components internally for its power supply, it will need AC. They probably supplied an AC adapter originally for a good reason. Your modem. Your risk. If you know what you are doing, open it up and check the circuitry. |

| 286749 | 2004-11-02 00:08:00 | Many modems took 16-20V AC from a power brick ... straight into a bridge rectifier. No problems with DC as long as you've got enough volts. (I've even built gear like this myself, so "any" power brick would work). Open up the modem and have a look at the components around the power socket first, if you have any doubts :D The manufacturers put the transformer in the power brick (to cater for the different AC mains voltages around the world). They didn't put another transformer in the modem. That would have cost money. |
