The power at both ends of the transformer is the power at the input and output sides of the transformer. Specifically, the input power is the power absorbed by the transformer from the supply side, while the output power is the power supplied by the transformer to the load side.
Ideally, according to the law of conservation of energy, the input power of a transformer should be equal to the output power because the transformer only converts between voltage and current without consuming or generating additional power. However, in practice, the input power tends to be slightly greater than the output power because of some losses in the transformer itself (e.g., iron losses, copper losses, etc.).
Transformer power unit is usually watts (W), for large transformers, sometimes also use kilowatts (kW) or megawatts (MW) to express.
