Holy Canolli! I went to bed at thirty something units and wake up to see it doubled!

Nice going folks!

I think we found a 100v equivalent MOSFET from Infineon.

BSC040N10S5

 

[jhofland]

Some folks have pointed out that the 60V rated MOSFETs may be limiting for amplifiers with higher rail voltages. We are changing to 100V rated devices.

 

[Berny]

Would PCBs only also be an option? It all depends on price in the end, but above an equivalent of 21 euro value, shipping included, import charges and duties start adding...

 

[xrk971]

Sorry, no bare PCBs on this one, just premade RTR units.

Can this be used with bridged amps?

 

[xrk971]

I will let jhofland answer, but I think on bridged amp, both wires are "live", so you might need two of these and don't connect the ground pass-through connector to any of the speaker wires. Just connect the supply ground and power source and one speaker wire through the SRR switch side.

 

[astromo]

I make it clear from the outset that I often miss detail that's obvious to others.

How is the board placed in the overall circuit, in terms of where it sits in relation to incoming mains power, transformer, amp PCB and speakers?

The way I'm reading the base detail is that one board per channel is required.

Pardon my confusion because the diyAudio Store equivalent has the soft start between the mains and the transformer and the speaker protection between the amp PCB and each speaker. I'm just trying to relate this bit of gear to an architecture that I currently understand.

Thanks in advance.

 

[xrk971]

It goes after the amp’s speaker outputs and before the speaker terminals. It needs a connection to the amp’s +ve supply from the PSU. This provides it the power to work and do its thing. It does not have a soft start - that’s part of the power supply. What it has is a delay that doesn’t connect the speaker until after 3 seconds to allow the amp to release its start up transient with the speaker not yet connected.
