The power supplies of the PSW250 series are powerful and robust devices with linear controlled output voltage. Under assistance of linear regulation transistors, the smoothed DC voltage is converted into a highly stabilized output. The disadvantage of this circuit principle is the relative high loss of energy into heat. For this reason a maximum of 30% to 50% efficiency can be obtained.
