Product Specifier

This Product Specifier walks you through the transformer selection process. For all things ballast related, click here.

When trying to specify the transformer you are looking for, simply select the feature you need from the list below. For immediate assistance, consult the support area on our site or call our Technical Services department at 1-800-892-3755. For definitions of specifier terms click here.

Step 1:

Determine whether your application is Single-Phase, Three-Phase or Industrial Control formula to find the appropriate KVA.

Step 2:

Enter the secondary load Voltage and Load Amps.

KVA needed:
1000

Important: The KVA of the transformer should be equal to or greater than the KVA of the load to handle current requirements and to account for future expansion.

Step 3:

Now select the Line (Primary) Voltage. This is the voltage from the source.

If your specific voltage isn't shown, select the next highest voltage from the list:

Line Voltage:

A few basic definitions:

  • Transformer size is determined by the KVA of the load.
  • Load voltage, or secondary voltage, is the voltage required to operate the load (lights, motor and other devices).
  • Line voltage, or primary voltage, is the available power from your utility or local power source.
  • Single-phase has two lines of AC power.
  • Three-phase has three lines of AC power, with each line 120 degrees out of phase with the other two.
  • KVA is kilovolt ampere or thousand volt ampere. Smaller units 500 VA = 0.5 KVA.
  • Enter either Load Amps or KVA needed.
  • Use the TAB key to move between fields.
