AUTO-TRANSFORMERS
for 125, 208 or 250 Volt, 60 Hertz Applications
50 Hz can be designed

Auto-transformers are frequently used to convert local Power line Voltage to some other Voltage value needed for a particular piece of equipment.

Most often, this conversion is from 125 Volts to 250 Volts, or 250 Volts to 125 Volts. Also, conversion from 250 Volts to 208 Volts or from 208 Volts to 230, 240 or 250 Volts is often required.

Tapped autotransformers offer the opportunity to more closely tailor the voltage conversion to existing equipment requirements.

Unlike an Isolation transformer, auto-transformers use common windings and offer no interference or disturbance isolation. You add any Suppression or Filtering networks your system requires.

A given size transformer will support a load equal to its rated value whether it is connected in the125 Volts to 250 Volts configuration -- or -- in the 250 Volts to 125 Volts configuration

These units are employed in custom designs or when converting industrial / military equipment between various operating voltage systems

Studies Show ...................

Winter Storms Cause More 
Wild Power, phone line outages, surges, spikes and interference
than Summer Storms

On the other hand, There are more Summer Storms

Winter Storm Spherics cause up to 50% as much damage as Summer Lightning Storms

On the other hand, WHY SUFFER ANY STORM DAMAGE ?
