TTs series transformers are meant to supply very low tension circuits. The secondary nominal tension and the vacuum secondary tension must not exceed 50V. The constructional specifications are identical to the normal trasnformers with the exception of ahaving: reinforced insulation, an increased insulation distance and the possibility of having an extra antistatic screen between primary and secondary.
On request the dimensions can be changed in order to fulfil any volume requirement.
