SSR for Heated bed
-
I have a 3D printer with Duet 2 WiFi, a PSU 24V 20A and a 24V Heated bed, connected to the duet output. My question is if there Will be any benefit installing a DCDC SSR to the bed heater.

@JBJBJB82 Not particularly, assuming that the bed draws less than 15A. Check that you have good connections into the bed heater screw terminals; poor/loose connections can generate heat. The Duet uses a MOSFET to switch the bed heater on and off, which can usually be switched at a higher frequency than an SSR.
If you did split it, you could have one PSU for the heated bed, and one for the electronics. See https://docs.duet3d.com/User_manual/Connecting_hardware/Heaters_bed#connecting-a-bed-heater
