Electricity 101

[zem]

I need to know how much 24v 100w DC draw would require in 220v AC power? It proved tricky to find this info and i would appreciate some help. Thanks!

Are you trying to figure what driver you require for an LED light run on 220?

The risk of death or fire or dying in a fire is real........have fun.

What exactly are you trying to do?

I am installing roll up motors for the greenhouse that are rated 100w 24v dc.

So are you planing on using step down transformers from 220 ac to 24v dc?
Is there a tech line you can call for the motors and ask a technician what they recommend ?

I have it all installed with transformer and proper cable and timer and relay to switch polarity. When you switch polarity on a dc motor it simply rotates the other way. I only wanted to figure out how they calculate actual draw of 100w 24v dc from 220v AC. I also don't have much time on my hand for extensive research into physics formulas but i couldnt find a direct conversion on online calculators. It is not a big priority though since i know i have the proper gear just wanted to know actual draw.

OK I was not aware of that, Glad it is all hooked up and working
Did you ever figure the actual draw was it much less than 100w?

I quit my research for now will try ask some electrician and will let you know

I thought you knew about electrical issues.

Seriously, you hou have helped me before.

@joeb631a is an electrician. Tagging him to see what he says. @CrashMagnet too since he is a mad scientist engineer type.

Still scratching my head trying to figure out what values he was looking for. I missed something
But yes @Tattered Old Graywolf is the man for this

Yup, now I know everything there is to know.
