How many amps is a 150 kva transformer good for?
| Three Phase Transformers, Full Load Amperes (FLC) | ||
|---|---|---|
| KVA | 208V | 480V |
| 75 | 208 | 90 |
| 112.5 | 312 | 135 |

How big is a 150 kva transformer?
150 VA, 1-Phase, 240 x 480 Primary Volts – 120/240 Secondary Volts, NEMA 3R, Isolation Transformer, Totally Encapsulated, 50/60 Hz. HxWxD: 7.16″ x 3.89″ x 3.67″.
How do you size a step up transformer?
If a transformer needs to step-up 240 volts to 480 volts, and you need a maximum current capacity of 40 amps, you must first calculate the number of amps needed to comply with electrical codes. If the codes require a maximum usage of 70 percent of the transformer’s capacity, multiply 40 times 1.43.
What is the purpose of a step up transformer?
A transformer designed to increase the voltage from primary to secondary is called a step-up transformer. A transformer designed to reduce the voltage from primary to secondary is called a step-down transformer.
How do you size a step down transformer?
Calculate an example as follows. A 120-volt motor has a load amperage of 5 amps. Multiply 120 volts times 5 amps this equals 600VA now lets multiply the 125 percent start factor. Take 600 times 1.25 this equals 720VA and most transformers are sized by a factor of 25VA or 50VA.

Do I need step up transformer?
You will need a step-down voltage transformer if you’re traveling to any country with a power standard that is higher than what your appliances use. Conversely, taking appliances that run on 220–110 volts to the U.S. or Canada requires a step-up voltage converter that can transform 110–120 volts up to 220–240 volts.
