We have a brew system we are attempting to automate via 12v DC solenoid valves.
These are connected to a PC Power supply thats 400w. Each of the 10 valves pulls 1 Amp, and if you do the math, the PC power supply can theoretically support all of them on at the same time.
We custom wired the PSU into our system to get the 12v out of it and it measures and test as working fine. It cannot however, power any of the valves. An older and much smaller PSU has no problem powering any of the valves, and does so with a solid *thunk*
After talking to an EE friend of ours he suggested that the PSU is both nice and new and has current limiting protection. Since the valves are demanding ~1A all of a sudden it trips the protection and we have to unplug the PSU and wait for it to reset, hence strange results in metering with a multimeter.
So here is where we need help from others here who might have experience with 12v power supplies, how can we best get a 10A PSU in our current system or modify the existing PSU so that it works with the current setup?
