Product Availability: In Stock

Starting at: $159.99

Todd Systems has been manufacturing transformers for industrial environments and the military for over 40 years. All Todd Systems transformers are designed and manufactured in the U.S.A. All Todd Systems transformers are precision wound and insulated with the latest hi-tech, insulating materials. The core laminations are of high grade annealed silicon steel, designed to keep heating to a minimum. All transformers are impregnated with a modified polyester heat cured varnish, which seals the transformer, thus protecting the electrical windings from moisture and contamination.

  • Designed and made in the U.S.A.
  • Manufactured to military and industrial specifications
  • Used by all branches of the U.S. military
  • UL Listed components
  • Fully rated at 50 or 60 Hz
  • Suitable for use in harsh environments
  • Three cord options available, optional TEMPGUARD thermal protection

If you need to operate a North American 110-120 volt appliance in a country where the voltage supplied by the electrical outlets is 220-240 volts, you need a step down transformer. Step down transformers take the 220-240 volt electricity supplied in most countries, and convert the voltage down to 110-120 volts for use by the appliance.

PLEASE NOTE: All Todd Systems products are "custom built" in that, while base models are stocked in large quantities, configuration options (such as power cord length/type, etc.) are installed on a per-order basis to suit the particular configuration desired. This is usually accomplished quickly, with the product shipping within 24 hours, but that varies from day to day based on volume. Therefore, we ask that you ALWAYS allow for at least 2 or 3 days lead time to ship.

About TEMPGUARD, the ultimate thermal protection against overload:

  • If an appliance exceeds a normal transformer's VA (wattage) rating, the transformer will eventually overheat and burn out, destroying the transformer, and potentially creating a fire hazard.
     
  • A TEMPGUARD transformer turns itself off automatically before any damage can be done to the transformer from overload and subsequent overheating.
     
  • After a TEMPGUARD transformer cools down, it will turn itself back on automatically.
     
  • A TEMPGUARD transformer will continue to turn itself off and on when the thermal threshold is crossed, with no damage done.
