Currently (no pun intended) I am using an Astron VS35M which gives me a linear, fully variable (both voltage and max current) metered supply. It's a workhorse and the size is perfect for my shack.
I also have a decent switching 35 amp supply as a backup. 73 Lyn, W0LEN -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Bob McGraw K4TAX Sent: Friday, April 17, 2020 2:50 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Electrolytic Capacitor failure All of my supplies have both voltage and current meters and they are in a position I can see them when I turn them on. With supplies which do not have meters, when one turns them on, you never know in advance and get what they deliver. In my case, I observe the meters BEFORE turning on a radio. On more than one occasion this has saved a radio due to a power supply regulation failure. Dumping 24 to 32 volts into a $3000 radios is not very pretty. Oh yes, the supplies do have OVP, Over Voltage Protection, but I've seen this fail as well and I've repaired several supplies where this did fail. And one doesn't know it has failed until the voltage goes to maximum value. Its too late then to find out the OVP circuit has failed. A meter would have prevented radio and accessory equipment damage. 73 Bob, K4TAX ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
