what is a multi tap transformer
Multi-tap Industrial Control Transformers are designed to provide stock flexibility for users whose equipment may see many different supply voltages throughout it`s life. Some purchasing agents like to use the multi-tap Transformer so they would only need to stock and purchase one Transformer, rather than two or more. However, that is not usually beneficial for the customer as multi-taps are more expensive, heavier, and larger than standard single or dual input/output CPTs. More often than not, 95% of their business is the standard voltage combination of 480 to 120, the D1 voltage code. As such, the D1 also happens to be the highest volume mover for Square D/Schneider Electric, and is priced to reflect this economy of scale. Thus if a purchaser chooses to only use the multi-tap, they are basing a decision to raise their cost on 95% of their product for only 5% of their business.
