Power Transformers

Industrial power transformers are commonly used with American Rotary phase converters.  In North America, most three phase utility service is nominal 208 volts, while single phase utility service is nominal 240 volts.  A phase converter will change the phase (for example, from single phase 240V to three phase 240V), but a transformer may sometimes be necessary to change the voltage of the system (for example, 240V utility can be changed to 208V with a transformer).

  • Distribution transformers for phase converters

    Dry Type Distribution Transformers

    Dry-type distribution transformers are rated for 600 volts and below, support a variety of general loads, and can be either ventilated, totally enclosed, or encapsulated (potted). Dry type distribution transformers can be used with American Rotary phase converters.
  • American Rotary Buck Boost Transformers for Phase Converters

    Buck Boost Transformers

    The advantages of using a buck boost transformer with a rotary phase converter (or other application) over an equivalent standard isolation transformer are numerous: used in a variety of applications, inexpensive, smaller, lighter, more efficient, and offer 5-10 times increase in kVA. The disadvantages are that there is no circuit isolation, cannot create a neutral, KVA and voltages do not match what's on the nameplate kVA and voltages.
