Linear Power Supply exist to provide four separate and distinct functions:
Change the output to a different voltage level than the input (step up or step down)
Rectify ac into dc
Isolate the output from the input
Stabilize the output against the influence of:
Source changes (source effect)
Load changes (load effect)
Temperature changes (temperature effect)
Passage of time (time effect or drift)
Linear power supplies are about 50% efficient. Only the smallest linear power supplies are capable of being securely mounted to a DIN Rail. Linear power supplies are still popular today because they provide very tight regulation (.01% typically), almost perfectly clean DC, fast transient response and their low component count helps provide a lower material cost for its user. Linear power supplies are typically open frame because of the excessive heat dissipation from their low efficiency.
