Was hoping for a simple answer/guidance.
What module/type of setup does Emotiva use internally for the 12v trigger on their amps? Is it a custom made PCB (individual relay, etc) or an all-in-one module?
I ask as I am putting together some custom Class D amps and looking for a trigger that can handle 15A @ 125VAC. All of the quality ones by reputable companies I have found either require you to build your own PCB setup using a stand alone relay or modules that only handle 10A.
There are a lot of cheap modules out there that handle 15A....but they are suspect at best.
Just thought I'd as on here since the community is pretty helpful and open.
Thanks!

I just built this. The relay I used is rated for 30a and seems quite robust. I previously built a version of this using solid state relays rated at 40a but I do not recommend this. While the solid state relays were rated sufficiently for the job, they do leak some current when in an untriggered state (nothing wrong with the relay this is just inherent to any solid state relay based on what I have read). For my purposes the current leakage was enough to trigger the power supply off and on intermittently. You can get around this by wiring a bleeder resistor across the load but using an electromechanical relay is the better solution as it is really the best tool for the job. If you are building your own amps it would be very simple to integrate this relay and design into your box. |

Just use the 10 amp relay to drive a 15 amp relay.

You still have plenty of extra space in your trigger box. You could add some colorful VU meters.  |

Just use the 10 amp relay to drive a 15 amp relay. I totally agree with using two relays. I made an external trigger box using a 12VDC trigger relay to trigger a 125VAC 30 amp relay for less than $50. I used the ET-3 to isolate my homemade box from my RMC-1.  |
