24 volt dc power supply circuit diagram schematic
This circuit shows how to build your own 24 vdc power supply with 2 A (ampere) current. The transformer of TR1 lowering the voltage of 230V with 24V secondary voltage on a transformer.
In the photos above you can see a schematic of 24 volt dc power supply that have rectification and filtering at 32V to 34V (depends on voltage and transformer)
