The MOSFETs will be hard ON all the time- you don't have to worry about bandwidth, as the resulting circuit will be good from DC to well past 100KHz. They have some capacitance associated, but that will be negligible unless your amp is really high output impedance!
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

Unfortunately, these are about $220 -> $320 on average: https://omronfs.omron.com/en_US/ecb/products/pdf/J144-E1-05.pdf Hopefully an SSR will replace this. |
