How to size a step down transformer
WebEfficiency is calculated by dividing the output real power by the input real power. The efficiency will vary depending on the amount of load because the copper losses of a transformer vary with load. Step# 1: Determine the transformer kVA, total copper losses, and total iron losses. WebJul 31, 2024 · If your transformer is rated at 1.5 kVA, and you want to operate it at 25 volts, multiply 1.5 by 1,000 to get 1,500 and then divide 1,500 by 25 to get 60. Your transformer will allow you to run it with up to 60 amperes of current.
