Industry Leading Warranties

Many of the Semper Fi transformers are backed by industry-leading warranties of 25-years (indoor units) and 10-years (outdoor units).

A magnetic transformer in its basic form is a core and coil that steps AC voltages up or down. The number of turns around the core (turns ratio) determines performance.

DC voltage produced is full wave rectified DC (unregulated and unfiltered).
For constant DC voltage, utilize the Power Modules.
For constant DC current, utilize the RPK Drivers.
