Hello

I purchased the (2) DP50V5A NC Regulated power supplies. I hooked them up to a 30V 20A power source. I tested each one out separately and they seemed to work fine. But when I ran both together, one at 14.5V 3A and the other at 5V 2.5A I blew a 10A fuse I had hooked up to them to protect them. Now the one still is working correctly, but the other one powers up with the display reading the same as the input voltage. Even when the on/off button is off. And when I turn it on and try to adjust it, nothing happens. It stays at the 30V 0A reading. Did I blow the circuit? or is there something that I am missing.

Any help would be greatly appreciated.

Thank you,
Tim Ambs
