I have an assortment of used and new Bosh, P&B, Siemens, Grundig etc....they are all 12-24V DC rated.
So I got to thinking I know scarry right? I do not have anything in the rest of this rig that is 12 or 24 volt DC everything in here that needs a voltage to trigger it is AC. So I was wondering if you guys normally just run with 115-120V relays so as not to need another rectified power source. My heater can use DC or AC I was going to run ac to it. If I run DC well that would take care of the relay and the heater.
Does one typically get a cleaner signal with DC to the heater instead of AC?
Also has anyone used a lot of solid state relays? If so what did you think compared to either open frame relays and vacuum sealed relays? In automotive CPU's I have had a lot of failures with solid state relays but at the time VW and Porsche where really putting it to their suppliers for cost savings. So I do not want to judge all solid state relays based on that one small sample size with just one company really!
From a mechanical standpoint it sure seems like they would or should be more reliable and not have the bounce associated with mechanical movement points type relays?
If you do like solid state relays what brands do you recommend. I know their is always a few companies at the top a few in the middle and a lot at the bottom of the quality control game. I would rather avoid the guys at the bottom but do not need to shop at the top either.
Also I was wondering if I buy used vacuum variables or used air variables is their someone on here that could high pot test them if I paid the shipping both ways? If not is their anyone in Michigan I could take them too to let them check them out. I would prefer not to get them into the circuit and then after putting power through the thing find out they are bad!!! Their are no shop's in my area that I would trust really to do a good job. I am sure their has to be some place in Michigan though that cater's to this type of market???
