The best way to convert 120 vac to 24vdc With at least 10 amps at 24 vdc?
I am buying a generator (probably 1000watt-1500watt) i want to hook up to a 24vdc gocart with 2 12vdc batteries in a series and have atleast 10 amps t...
I am buying a generator (probably 1000watt-1500watt) i want to hook up to a 24vdc gocart with 2 12vdc batteries in a series and have atleast 10 amps to power the mottors What would be a good cheap way to do this.
While buying a ready made power supply would be simplest, a regulated supply might be overkill for running a motor, a transformer and a bridge rectifier might be all you need. Transformers made for buck/boost use are pretty easy to find in this current range, and fairly high current rectifiers are easy to get, but be sure you heat sink the rectifier, it will get warm at 10A.
While 24V battery chargers are not as common as 12V ones, if you could find one it might work even bettter, especial if it has an engine starting (high current) mode, as your DC motor will likely have a high starting current, you will still be limited by you generator output, but 1000W is 83A @ 12V. A 10A regulated supply will probably be current limited at 10A making your acceleration from a stop rather poor.
An open frame linear power supply is probably the cheapest solution for you. One such supply can be bought from Allied Electronics:

Make sure that when you connect the supply that you first disconnect the batteries. If you don’t and the supply is connected directly across the batteries, you may have an explosion.
