Power Supply Soft Start Board (V3)

Finally got around to building the soft start board. :D

I had ordered the parts back in late May, and the parts bag has been sitting on the bench since then.

I am going to use it to power the 400VA transformer in my DIY Linear PSU, shown in the second image. It is still in the prototyping stage but with winter approaching I should have more time to work on my projects.

Initial testing look pretty promising. In case you are wondering I 3D printed a standoff as I was uncomfortable with the 120V on the traces along the underside of the soft-start board being so close to the metal chassis insert.

For any wondering I did end up using the Panasonic relay I was inquiring about above and it works great.

Hello , could you check my speaker protection board connection. Blue and brown to 12 VAC transformator, yellow to PSu ground. In this configuration delay works good but i Don't know if dc protection is also OK, because I did test with 1,5V battery ( + to IN on board and - to chassis) and relay did not disconnect speakers. Thanks for help in advance
