The switch-mode power supplies of the SNT5024 series are powerful and robust devices to power sensitive loads in a hard industrial environment.
These features result from the modern construction with a good radio shielding and high reliability integrated in a functional and stable casing.
The short circuit proof output DC voltage of this model can be adjusted from 22.5 to 30.0 V. This power supply is optimally suited for loads requiring high starting currents.
Functional principle
In the power supply SNT5024 a flyback converter operates to transform the energy in two steps.
During the conducting phase the diode is blocking, the inductor is energized and a magnetic field establishes. There is no electrical transmission; the consumer load is supplied with energy from the capacitor.
When the switching transistor opens, the blocking phase begins. The current in the inductor cannot change immediately, discharges through the diode and a negative voltage establishes atthe inductor.
Now operating like a power source the inductor reloads the capacitorand supplies the consumerwith energy. The energy flows from the inductor into the capacitor and the consumer and through the conducting diode back to the inductor.
