This question is aimed to TRUE Elec Engineers, not fuse or wire directionality believers.


Has any of you ACTUALLY worked with and recommend a SSR which does not introduce any audible distortion on the speaker line and which can operate with a large range of trigger voltages (12 - 48 VDC, may need to have on board voltage regulator for this range).  I am building a speaker DC protector and do not want to use electro mechanical relays becoz of DC arcing and contact erosion issues.  It needs to be capable of switching up to 15 amps at about 100 volts.

Only TRUE engineers reply please.

Thanks

It’s an expression used by someone who still thinks there’s room for argument regarding aftermarket fuses and fuse directionality. A renegade. A refusenik.

- As for the NASA fuses/relays, I know about them, they are
encapsulated in nitrogen under pressure so that they MAY be
able to break DC but they cost in excess of $200 or so for a
15 amp relay.

>>>>Nice that you know all about them but apparently what you don’t know is that advanced audiophile fuses can oft exceed $149 and sometimes even exceed $200. Maybe NASA needs to step up their game. Audiophiles have two or maybe three conflicting requirements, cost, sound quality and protection.

Even NASA uses fuses, just like most everyone in high end audio does. Fuses have come a long way, baby. NASA started studying advanced fuse concepts twenty years ago which, ironically perhaps, is about the same time advanced audiophile fuses were introduced. Coincidence? Now, NASA might not give a hoot about sound quality but audiophiles certainly do.

Aerospace engineers oft outperform EEs, for example directionality and fuses.
