The switching power supply is by far the most popular power supply for industrial applications today. Most switching power supplies are only 25% the size of an equivalent linear supply, and they are 25% more efficient. This makes the switching power supply the best choice for most industrial applications. The power output, Watts, of the power supply, is often specified incorrectly. The required dc power for the application should not be a guess.
Specifications
In most cases, the input voltage is universal, accepting 85 to 264 Vac, 50/60 Hz and typical outputs are 5, 12 and 24 Vdc with 24 V the most popular for industrial applications.
