The efficiency of primary switched-mode devices is 80% to 90% - much better than the
efficiency of linearly regulated devices. Therefore, in a primary switched-mode device
less heat loss is generated and the relatively small transformer needs to provide only a
small amount of dissipated power.
Light and compact
Example
Circuits based on the primary switched-mode controller principle enable the design of
extremely light and compact devices.
Primary switched-mode devices are intended for general use in the field of automation
technology. Low heat loss, compact design and a wide input voltage range make these
devices ideally suitable for use in distributed junction boxes.
The following example will illustrate the advantages of primary switched-mode power
supply units in contrast to linearly regulated devices by comparing the power dissipation.
Modern primary switched-mode power supply units have a typical efficiency greater than
90%. This results in a total power dissipation of only about 75 W for an output voltage of
24 V DC and an output current of 40 A.
The typical efficiency of 50% of a linearly regulated device results in a power dissipation of
about 500 W. Dissipation occurs in the form of heat, which causes the control cabinet
temperature to rise unnecessarily.
