Important Notes:

• This calculator assumes a linear relationship between load and voltage regulation.
• Actual performance may vary based on transformer design and operating conditions.
• Always leave a safety margin when using transformers near their rated capacity.
• Consider heat dissipation when operating transformers at high loads for extended periods.
