Let us know!

To avoid confusion, we try not to interchange these words because each item is slightly different from the other.

Typically a "transformer" is simply a magnetic core and coil that steps AC voltage up or down.

"Power supply" indicates that there are electronic components included. Electronic transformers, ballasts, constant voltage units, and drivers would all by types of power supplies.

When we refer to a "power supply" we typically are referring to our power modules, which produce a dimmable constant DC voltage output.

A "driver" has become a generic term used to describe constant voltage and constant current power supplies. To avoid confusion, we use "drivers" to mean our RPK constant current power supplies.
