How to change from a two-phase network (Phase + Phase) to a single-phase network (Phase + Neutral).

Converting an installation with two phases (two-phase network) to another network with phase and neutral (single-phase network) is very easy to do thanks to our single-phase isolation transformers (“P”, “Q”, “N”, “PXR” and “TK5IN” series).

This need arises mostly because a machine (air conditioning, boiler, etc.) whose control board requires an isolated neutral must be supplied.

To carry out this procedure: we will use a single-phase transformer with the appropriate power, which we will connect in the primary with the two phases and at the output, we will make a bridge between one of the phases of the output and earth. From this moment on, this line will act as neutral.
