Step down transformer
In our move to Portugal I have a lot of 120v tools, one of which being a couple of DeWalt cordless drills. The chargers are 120v, they offer a EU spec 240v version but none of the local stores have them in stock.
Could I not simply just wire in a step down transformer and be done? Here is an example of one: chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://pt.mouser.com/datasheet/2/643/ds_st_eb_of_series-1315092.pdf If so I can use most of my tools there; ie portaband, chopsaw, etc. |

Just be aware that they are also 50hz. Better off with a power supply instead of transformer.
Watch your watts when you buy. Stan. |

I looked at power supplys; once you get high enough to do anything useful the price really goes up or the quality goes down.
Most of the stuff I need to power is pretty simple. |

My father in law did something along those lines when he moved to Peru. Unfortunately, he's losing his memory, and when I asked him about it, he didn't know what I was talking about, so I can't provide any useful information.

A wirewound stepdown transformer for 50Hz will work fine. Too had about the 50 Hz, but most motored items should be fine. Brief on-time is no worry. On for >20 min and i would monitor how hot the motor get.

The only thing I would add is to be aware that some electronics won't like the 50hz power. Things like cordless tool chargers and such may not work or fail on 50hz. I would ask the manufacturer before moving on suspect items and sell the ones that you can't confirm will work prior to moving.

The charger is the main bugger in this - I am trying to buy a EU spec unit here as the DeWalt units there are all out of stock.
But I thought for motored stuff the step down will suffice. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
