Questions & Answers

24 volt ac or dc?

This transformer is AC

Can I use this transformer to my 24 volts lawnmower I like to convert to 110 electronic

Asked by: Abdul
Your lawn mower probably has a big sticker on it that says something like 10 amps, or maybe more. It may be on the battery - something like "20 amp hour." Just to put things into perspective, this transformer can only deliver about 1.5 amps. If you connected it to the lawnmower, it would heat up, and it's internal overload protection would shut if off, if your fortunate. It could start a fire, electrocute you, and damage the lawn mower. You also have another problem, this device puts out AC power, not DC, and your lawn mower needs DC.

Is it in store?

Asked by: Dado
It was in my local HD. But it’s not in the usual doorbell section. I found it in the HVAC section since it is also commonly used to power newer Smart thermostats
