hi
recently ,I've been working on a project in which i should parallel about 100 solenoid valves . but , there's a problem! when ever I try to turn on more than 5 valves together, my power supply turns off! i'm using a PC power supply and each solenoid needs 1 amp current to open and 0.3 amp to stay open and I'm using a (TIP122) to drive each solenoid valve.
I know that the current that this power supply gives me is not enough for my project at all and also the voltage. but i can't find an easier and safer way than using these kind of power supplies. I specially shouldn't use 220V in this project because of safety issues and i couldn't find an ideal power supply and circuit for it. I need somebody's help on this issue...
how can I make a power supply that can supply the power needed for this project?
what's the circuit?
what's the best way to parallel the solenoid valves?
having said these ,I'm controlling these solenoids with an ATmega32 micro.
you may help me?
thank you
