That's what I have done here. I have a 20 amp VJ Products and a RS-35 Astron. I have them in parallel and fed in to a home brewed distribution box. I had often wondered if the difference in current rating would create any problem. Also, I have never checked to see if they both have exactly the same output voltage. Would either of the above present any problems?

My K2/100 runs 16 to 18 amps from my Astron 20M. 2) Large supplies (even the 20 am, but especially one like a 50 amp) can be very dangerous! While you won't get a shock from 13 vdc, they require all the care you'd exercise working with an automobile battery. Shorts can cause instant fires. Hot, molten metal spraying, splattering and dribbling all over the place from a short can burn lots of holes in things, including your own body and eyes. Shorts tend to become instantly welded in place and if it's not good enough to cause the crowbar circuit to trip, the power supply will keep dumping current into the circuit. An RS 50 supply will dump 50 amps into a 0.3 ohm short nonstop. Fuse everything and be careful just the same. 3) You might get more amps for your buck by buying two or three smaller supplies than one big supply, and thereby be less likely to experience a total failure if a supply dies on you.
