Re: Transformer for 110v power tools?
|
Text of the message: |
Regarding the 120V AC/DC, I suspect the device uses an internal 'full wave rectifier' creating a DC source. Therefore it would not be frequency sensitive. You will still need a transformer capable of 50 Hz. In addition to devices who's speed is determined by the AC frequency, a 50Hz source spends a longer time per cycle above or below a given polarity. When the AC power goes through the transformer there is a likely hood that the magnetic core will saturate. When that happens there is no more resistance and you will get a current spike possibly burning out the transformer. A 50Hz source requires larger transformers because it requires a larger magnetic core. You might be able to use a 'Google' search to locate a 2:1 transformer capable of 1800+ watts, 50Hz for a 220/120 conversion.
