Using the SDP4-24-100 as an example, the detailed application and fulfillment of the NEC requirements for Class 2 power sources is portrayed. 1 is a circuit diagram illustrating the electrical connection of componets of an embodiment of a DC power supply circuit. •Switch Mode Topologies. Simply put, designing a power supply is a major undertaking. ANTONIAZZI In mains-supplied electronic systems the AC input votlage must be converted ni to a DC voltage wthi the right value and degree of stabilization. In this situation we have to use a DC POWER SUPPLY.
