All four windings are identically rated at 0/104/110/120 V. This permits series or parallel connections on either primary or secondary. Therefore, a nominal 110 V to 110 V, 220 V to 220 V, 110 V to 220 V, or 220 V to 110 V transformer can be configured. The winding tap permits intermediate series ratings such as 208 V, 214 V, or 230 V. It is also possible to make auto-transformer connections by connecting a primary group in series with a secondary group. Such nominal ratings as 440 V to 220 V or 220 V to 440 V can be configured in addition to the standard ratings described above. A further advantage to auto- transformer connection is the fact that the kVA rating of a particular type is doubled. * USR component transformer evaluated to the standard for General Purpose transformers, UL 5085-1, UL 5085-2 for construction, spacing and insulation system. Provided with a Class 105 insulation system. Transformers are intended for use in end-product equipment.
