DC to DC power supplies take a DC voltage input and convert them to a different DC output. If the conversion is from a higher voltage to a lower voltage the output current can be higher maintaining the same power minus the conversion losses.
Single output Power supplies take line voltage and provide regulated DC voltage as an output - See: Single-Output Power Supplies
Multi-output power supplies take line voltage and provide more than one regulated DC voltage - See: Multi-Output Power Supplies
This Din-rail mounting kit lets you mount several of our power supplies on din rail tracks. Just screw it to the power supply and you have a quick way to mount and unmount your power supplies...
