1. [Amps] Solid state relay question (score: 1): Author: rakefet@rakefet.com (Vic Rosenthal); Date: Sat, 15 Jun 2002 21:24:11 -0700; I have a Henry Radio SS750 solid-state amp that runs on 14v at about 100 amps max. I'm using a pair of Astron 70-amp power supplies in parallel (they have a sense input that permits this) to power th; /archives//html/Amps/2002-06/msg00104.html (7,804 bytes)

It would be interesting to see what the line voltage drop is with the amp keyed, with the S.S. relays bypassed and connected. Somehow, it seems to me, that your i; /archives//html/Amps/2002-06/msg00106.html (8,059 bytes)
4. [Amps] Solid state relay question (score: 1): Author: rakefet@rakefet.com (Vic Rosenthal); Date: Sat, 15 Jun 2002 22:34:21 -0700; That turns out to be the answer. After posting my original message, I noticed that it did NOT happen when I transmitted into a dummy load, only an antenna. The acutating voltage comes from a 78L05 re; /archives//html/Amps/2002-06/msg00107.html (8,089 bytes)

May be time to unhook those caps temporarily and redo the rf distribution until the relays no longer kick out. FWIW. Bill K2AME; /archives//html/Amps/2002-06/msg00109.html (7,862 bytes)
6. [Amps] Solid state relay question (score: 1): Author: 2@mail.vcnet.com (Richard); Date: Sun, 16 Jun 2002 06:48:09 -0700; The near-field from the antenna might be the culprit. I would go with conventional 24vdc mechanical relays and, since speed is not important in this app., use c. 18v on the coils. - R. L. Measures,; /archives//html/Amps/2002-06/msg00111.html (8,037 bytes)
7. [Amps] Solid state relay question (score: 1): Author: rakefet@rakefet.com (Vic Rosenthal); Date: Sun, 16 Jun 2002 09:00:50 -0700; You know, I don't think it's that kind of problem. The antenna I was using is a quad with a balun and I have absolutely no trouble with any other device in the shack -- computer, keyer, TNC, FM radio; /archives//html/Amps/2002-06/msg00113.html (7,929 bytes)

9. [Amps] Solid state relay question (score: 1): Author: w8ron@stratos.net (Ron); Date: Sun, 16 Jun 2002 21:08:09 -0400; Hi Vic. I use thes types of relays for many things. If you have the ones that actuate from 3 to 32 volts , it would be easy to get some interferenc from RF dropping the actuating voltage below 3 volt; /archives//html/Amps/2002-06/msg00123.html (9,375 bytes)
10. [Amps] Solid state relay question (score: 1): Author: rakefet@rakefet.com (Vic Rosenthal); Date: Mon, 17 Jun 2002 07:14:52 -0700; This one is rated 3-8v, although it said in the All Electronics catalog that it 'works on 12 volts'. However, I felt that it would be best to stay within the rating. I certainly can put a capacitor a; /archives//html/Amps/2002-06/msg00125.html (8,865 bytes)
