Cooling transformers | Choosing the Right Transformer
Power, primary voltage and secondary voltage are the most important characteristics of a transformer. Power This must for your circuit and the devices it’s composed of. Oversizing a transformer can result in significant no-load losses. Undersizing a transformer can reduce efficiency, cause windings to heat up or even accelerate the aging of the insulation, which can put the transformer out of service. This means you will have to determine the optimal power...
