"R.van Trotsenburg" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Hi Floyd, I do seen this happen in at least three other occasions in PS7 supplies. As long as the PS7 is not blowing it's fuses. It means that both crowbar and current limiter circuits are doing there job. 73, Rien PA0TRT
Message text written by INTERNET:[email protected] >Floyd Sense <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- After posting the question, I ran a test to see what the time was that caused the problem. If I turned on the TR7 in 5 seconds or less, it never turns on. If I wait 8 seconds or more, it always turns on. I've not noticed any other problems with the supply, so won't worry about it. I don't recall ever seeing anyone else mention it here, and thought that someone would have by now if all the PS7s acted that way. 73, K8AC [EMAIL PROTECTED] wrote: > Floyd - > > By turning the TR7 off and on rapidly, you trigger a "crowbar" which > will not allow you to turn the rig on until it (The PS) has time to reset. > > 15 seconds to reset seem a bit over exaggerated, but it is possible that > there may be a problem in the protective circuit. > > 73, > Jay/AF2C > > > > At 03:14 PM 3/16/2007 -0400, you wrote: > > >> Floyd Sense <[EMAIL PROTECTED]> made an utterance to the drakelist >> gang >> ---------------------------------------------------------------------- >> I have a small problem when using my PS-7 supply with my TR7.
