Easy Transformer Sizing

When purchasing a transformer you will need to know what size of transformer you need.  As a transformer manufacturer, we will help you in this process too, but this will give you an overall picture of what size you may need.  Determine the basic requirement for your transformer, including its load and line voltages, and load current or amps. Sizing a transformer is an easy task once you understand the language that is used. There are no hidden codes on the transformer, just abbreviations.

Step By Step Transformer Sizing

Transformer Sizing : Step 1 – Understanding the language. 

Certain terminology is used when sizing the transformer. The terms are easy once you understand the abbreviations. V which stands for Voltage - A (or Amps) which is Amperage  -  K which stands for Kilo which is equal to 1000.  If a transformer is rated at 120VA it means that it can handle 120 volts at 1-ampere or 1 amp of current.  The VA is short for volt-ampere a designation of power.  A transformer rated at 1.2 KVA is another way of say 1200 VA or 120 volts at 10 amps of current.


Transformer Sizing : Step 2 – Calculate the load you want to place on the transformer. 

All electrical devices come with a rated nameplate on them showing possible power usage. This is always described as voltage and load amps.  The load amps are calculated after the device is started and running.  All electrical devices have a starting current, which is usually higher than the running mode.  You need to take this in to consideration when sizing the transformer.  When figuring the load, always multiply the voltage times the load current and multiply a 125 percent start factor in the load.   An example of this would be if you have a 120-volt motor and a load amperage of 5 amps.  You would multiply 120 volt times the 5 amps this equals 600 VA now let’s multiply the 125 percent start factor.  Take 600 times 1.25 this equals 720 VA.  Transformers are sized by a factor of 25VA or 50VA.  The required transformer would be a 750 VA or .75KVA transformer.  Always figure a little higher in the VA capacity, never go lower or you could damage your equipment.

Transformer Sizing : Step 3 – Size the transformer for any voltage or amperage.

You can plug any voltage or current into the VA rating of the transformer. The nameplate rating will have a maximum voltage rating generally this is 600 volts for a transformer.  If you want to operate a transformer at 24 volts and it is rated at 120VA, then divide 120 VA by 24 volts.  The amperage allowed by the transformer would be 5 amperes.

As a quality power transformer manufacturer, we will help you figure what size transformer you need and will discuss with you any other factors that need to be taken in consideration for your application.
