Safety isolating toroidal transformer
Toroidal power transformer frequency: All of our transformers are designed for 50/60Hz.
Toroidal power transformer voltage regulation: this is the power lost (heat) in the normal operation of the transformer.
Voltage regulation=(no load voltage-load volatge)/no load voltage*100%
Example: no load voltage 18v, load voltage 17v. voltage regulation=(18-17)/18*100%=6%
A regulation of 6% means the transformer is 94% efficient
