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

I have +/- 90 Volt rails. This is more like it:I think you need higher voltage rating than 100V http://www.geofex.com/Article_Folders/ampprot/dcprot.htm |
the driver was working, prior to being connected to a 33uF, non-polarized film cap and a C cell. It was reading 6 Ohms(correct nominal, according to the tweeter’s label), before it opened up.1.5V across 6 Ohms = 0.25A or 0.325 Watt Back EMF? or Is the capacitor fully discharged before connect to the tweeter? |
