A single-phase transformer (with WAGO terminal) is an electrical device that accepts single-phase AC power and outputs single-phase AC. This is used in the distribution of power in non-urban areas as the overall demand and costs involved are lower than the 3-phase distribution transformer. They are used as a step-down transformer to decrease the home voltage to a suitable value without a change in frequency. For this reason, it is commonly used to power electronic appliances at residences. And we have equivalent to all Block’s transformers, quality is good and steady. There are JBK type, UI type, etc.
