Looking for a stable, heavy duty way of getting a 24V DC output between 25-30 amps.
It won't be used to charge batteries but instead to power an commercial 48v motor reliably for 2-3 hours once a month..
I'm not sure if a battery charger/power supply will suffice as a constant power source.
Any recommendations will be appreciated.

you looking for a 24V power supply to power a 48V motor?
if is a typo look on amazon or ebay for a power supply 24V output 40 A . make sure you check your supply voltage is 110 or 220 single phase .

Motor is very similar to this,

4.8hp @ 24v
10hp @ 48v
They didn't specify amperage rating at 48v tho but I'm suspecting it will be less...

Lot of radio control guys locally use these to provide high amperage for charging lipo batteries.

those in the article are 47amps
you can get server power supplies 55,75 amps
I had a 55 amp set and sold

This looks like a traction motor. A 1 HP motor uses more than 750 Watts. That's more than 15.5 A @ 48 V or 31 A @ 24 V. Yours is five times that.
Even at half capacity, you are looking at an 80 A supply. That is one big a$$ supply. You can either:
1. Swap the motor for a 230V AC single phase 5 to 10 HP motor (you can run the motor from a welding outlet wired directly to a circuit breaker panel)
2. Charge a bank of batteries with a 12 V charger to provide the necessary power at 24/48 V by hooking them up in series
3. Buy the power supply which is about the size of a small refrigerator. They are available from local suppliers. My guess on the cost is about TT$20,000

Of course I have no idea what his load is, so it's anyone's guess.pugboy wrote:didnt he say 30amps 24v ?
