This slide shows the wiring schematic for the MED series transformers. The input (primaries) can be configured for either 100V, 120V, 220V, or 240V input at 50/60Hz. This allows for the transformer to be used virtually anywhere around the world. One thing to keep in mind is that the primaries must be connected in either parallel or series configuration. This is in order to distribute the load evenly between the windings. Secondaries can be connected either in series for 240V output or parallel for 120V output. The output can also be used as two independent secondary windings. The electrostatic shield should be grounded. All leads are 10” long flexible leads.
