How do you calculate the amp output of a transformer?
Divide the wattage by the voltage. For example, if you have a 300-watt lighting transformer and you are going to hook it up to a standard 120-volt socket, divide 300 by 120. The transformer will draw 2.5 amps of current.
How much does a 45 kVA transformer weight?

Can you step up 208 to 480?
This transformer is designed to convert 3-phase 208v to 3-phase 480 Y 277 to run equipment such as panels, motors, CNC machines, welders, conveyor systems, pumps, printing equipment, fabrication tools, and other business machines.
How do you calculate the output of a transformer?
Divide the number of secondary windings by the number of primary windings, and multiply the source voltage by this ratio. This will give you the output voltage.

How many amps does a 45 kVA transformer have?
45 kVA Single Phase Transformer Amps when V = 1.1 kV. Amps = 45 * 1000 / 1100 = 40.9 Amps. In case of Three-phase 45 kVA Transformer. Amps = 45 * 1000 / (1100 * 1.73) = 23.64 Amps. 45 kVA Transformer Complete Chart for different voltage levels
How is the kVA rating of a transformer calculated?
Transformer capacity is rated in KVA (kilo-volt-amperes). The load voltage and load amps must be known to calculate KVA rating. * NOTE: We do not recommend loading a transformer above 80% of its KVA rating. When the KVA rating has been calculated, divide that number by 0.8 to get the minimum KVA rating needed.
How to calculate the size of a transformer?
HOW TO SIZE A TRANSFORMER Transformers are sized by determining the total load required (in amps). Transformer capacity is rated in KVA (kilo-volt-amperes). The load voltage and load amps must be known to calculate KVA rating.
What is the primary power of a 480V transformer?
Primary is 480 3PH , Secondary is 208/120. I will bond at the transformer case, core, and windings. The 125A panel that it will feed will have 3 phases of secondar … read more I have a customer supplying equipment for an E-house and I am unsure about these two systems.
